TeX is a software system written by Donald Knuth to typeset text, especially text containing mathematics. LaTeX is a set of macros written in TeX, designed to simplify the the typesetting of a document by allowing the user to concentrate on the content and structure of the document rather than the exact appearance of the finished product. METAFONT, also discussed here, is a program which allows the user to design their own fonts. The definitive reference for TeX is _The TeXbook_, by Donald Knuth (Addison Wesley, 1984, ISBN 0-201-13447-0, paperback 0-201-13448-9). For LaTeX, see _LaTeX, a Document Preparation System_ by Leslie Lamport (Addison Wesley, 1986, ISBN 0-201-15790-X); the second edition of this book covers LaTeX2e. Full documentation for LaTeX2e can be found in _The LaTeX Companion_ by Michael Goossens, Frank Mittelbach, and Alexander Samarin (Addison Wesley, 1993, ISBN 0-201-54199-8). For METAFONT, see _The METAFONTbook_ by Donald Knuth (Addison Wesley, 1984, ISBN 0-201-13445-4). The American Mathematical Society has two macro packages which are also popular, called AMS-TeX and AMS-LaTeX. This article contains answers to some frequently asked questions on comp.text.tex. Please don't ask these questions again, as they've been answered many times before. Malencontreusement, je n'ai ni le temps ni la comp\'etence pour traduire cet article en fran\c{c}ais. Je prie donc, le lecture interess\'e par fr.comp.text.tex d'avoir l'indulgence d'accepter la version anglaise. This is version 1.50 for January, last changed 1/9/95. This article includes answers to:  1) How can I get a copy of this article?  2) Where can I get a DVI to PostScript conversion program?  3) How can I include a PostScript figure in LaTeX?  4) Where can I find a DVI previewer for machine Y running Q?  5) Where can I get the manual for PiCTeX?  6) In LaTeX, I put some definitions in my document, but I get the error     ``Use of \@ doesn't match its definition'' or ``You can't use     \spacefactor in vertical (or math) mode.'' What's wrong?  7) What is OzTeX and where can I get it (TeX for the Mac)?  8) What is Fig and where can I get it?  9) How do I get WEB for C, FORTRAN, or some other language?  10) How can I typeset music in TeX?  11) What is TUG and TUGboat?  12) How do I convert Adobe's afm files to tfm format?  13) In LaTeX, how do I get a double-spaced document?  14) In LaTeX, how do I include a file in the verbatim environment?  15) In LaTeX, how do I do Y?  16) Where can I find a TeX macro or LaTeX style file for doing Y?  17) How do I generate an index in TeX/LaTeX?  18) How do I get METAFONT to do what I want it to do?  19) Where do I get TeX/LaTeX for machine Y running Q?  20) Where can I get a thesis style for LaTeX?  21) How do I get symbols for ``the real numbers'', ``the complex numbers'',      and so on?  22) What repositories of TeX material are available, and how can I      access them?  23) How do I use PostScript fonts with LaTeX?  24) How can I convert from format Y to TeX or LaTeX, and vice-versa?  25) How do I get a file into the major style repositories?  26) Where can I get font Y?  27) Where can I get a dvi driver for the HP LaserJet?  28) TeX and LaTeX are hyphenating words weirdly. What can I do?  29) How can I convert a TeX or LaTeX file into a plain ASCII file,      with all the formatting intact, a la nroff?  30) How do I enlarge TeX? I keep getting ``memory capacity exceeded''      errors.  31) In LaTeX, I used \pagestyle{empty}, but the first page is still      numbered. What do I do?  32) Where do I find documentation about BibTeX?  33) How do I use BibTeX with plain TeX?  34) How do I draw Feynman diagrams in LaTeX?  35) What is the New Font Selection Scheme (NFSS)?  36) In LaTeX, my cross-references for floats (figures and tables) are      incorrect. What's wrong?  37) I want to change the margins in LaTeX. What can I do?  38) How do I find the width of a letter, word, or phrase in TeX?  39) In LaTeX, is there a comment or ``ignore'' environment with which      I can exclude blocks of text from the .dvi file?  40) Where can I find a spelling checker for my TeX file?  41) What is LaTeX2e?  42) In LaTeX, how can I define a new log-like function?  43) In LaTeX, how do I put a \sqrt in my \caption statement?  44) In LaTeX, how do I get thin and thick \hlines in a table?  45) In LaTeX, how do I number the bibliography using Arabic numbers without      square brackets or using superscripts?  46) In LaTeX, why are my cites all numbered zero?  47) In LaTeX, my figures get put on a page by themselves with too much      whitespace, but when I tried \begin{figure}[t] they get printed at      the end. Why?  48) In LaTeX, how do I make a line break in a section title?  49) In LaTeX, how do I number equations by section? If you are looking, for instance, for the answer to question 17, and wish to skip everything else, you can search ahead for the regular expression ``^17)''. These are all legitimate questions, but they seem to appear too frequently for long-time readers of the list. Many of the answers below tell you that you can obtain something through anonymous ftp. ``Ftp'' stands for file transfer protocol, and is also the name of a program implementing the protocol. The program allows users to transfer files to and from remote sites, if the sites are connected via a network such as the Internet. ``Anonymous ftp'' indicates a user may connect to a remote site as the user ``anonymous'' with a password consisting of their email address, and thus be able to retrieve files from that site. Remember, anonymous ftp is a privilege and the system administrators for these sites have made these files available out of their own generosity. Therefore please restrict your ftp'ing to non-prime hours at the various sites. I would like to acknowledge Don Hosek, Ken Yap, Tomas Rokicki, Micah Beck, David Carlisle, and Donald Arseneau who provided many of the answers.  Joe Weening, Hal Perkins, Walter Carlip, Max Hailpern, Tad Guy, Raymond Chen, Henning Schulzrinne, Sebastian Rahtz, Mark James, Peter Galko, Mike Ernst, Rainer Sch\"opf, Oren Patashnik, Philippe Louarn, Rafal Zbikowski, Anita Marie Hoover, David Rhead, Darrell McCauley, Cameron Smith, Emma Pease, Patrick McPhee, Karl Berry, Robin Fairbairns, Joohee Jeong, Sam Steingold, J\"org Knappen, Barbara Beeton, Norman Ramsay, and Richard Mathar provided additional material and criticisms. The format of this document is based on the Frequently Asked Questions written by Steve Hayman which formerly appeared in comp.unix.wizards. Any mistakes are mine. Send corrections, suggestions, and additions to [email protected]. 1) How can I get a copy of this article?   You're reading it aren't you? SAVE it :-). This article is posted   monthly to comp.text.tex and cross-posted to news.answers. It is   therefore archived at any site that archives news.answers.   News.answers is archived on rtfm.mit.edu, and this article is   available there via anonymous ftp in the directory   ./pub/usenet/news.answers/tex-faq. If you do not have anonymous   ftp, send an e-mail message containing the lines ``SENDME FAQ.'' to   [email protected] ([email protected]).  Another way to retrieve   it via email is through the mailserver at rtfm: send a message   containing the lines ``help'' and ``index'' to   [email protected] for information on how to obtain it.   Other news.answers/FAQ archives are: cnam.cnam.fr (163.173.128.6)   in the anonymous ftp directory /pub/FAQ; ftp.uu.net (192.48.96.2)   in the anonymous ftp directory /pub/usenet (also available via mail   server requests to [email protected], or via uunet's 1-900   anonymous UUCP phone number); and ftp.cs.ruu.nl (131.211.80.17) in   the anonymous ftp directory NEWS.ANSWERS (also accessible via mail   server requests to [email protected]). Many of the archives   mentioned in question 22 also maintain current versions of this   document.   The UK TeX Users Group wrote an expanded version of this article   for their annals, Baskerville (vol. 4, no. 6, Dec. 1994). It is   available as a very nice Web page from the URL   http://www.cogs.susx.ac.uk/cgi-bin/texfaq2html?introduction=yes 2) Where can I get a DVI to PostScript conversion program?   Two good DVI to PostScript conversion programs that run under   Unix are:     dvips - by Tomas Rokicki. This driver is very nice and has the       ability to deal with virtual fonts. Available via anonymous ftp       from labrea.stanford.edu (36.8.0.112) in ./pub. Dvips is       written in C and ports easily to other operating systems.  It       is available for VMS via anonymous ftp from any CTAN site (see       question 22) and also through the DECUS library (see question       22). A precompiled version for MSDOS is available from       monu1.cc.monash.edu.au (130.194.1.101) in ./pub/dvips54.zip,       from shape.mps.ohio-state.edu (128.146.110.30) in       ./pub/msdos/dvips/dvips54.zip, or from any CTAN site (see       question 22) in ./systems/msdos/drivers/dvips.  If you wish to       use postscript fonts, get dvipslib.zip as well.  Documentation       is available in dvips.ps.Z. Karl Berry has a version of dvips       called dvipsk which has a configure script and path searching       code similar to that in his other programs (e.g., web2c).  It       is available via anonymous ftp from ftp.cs.umb.edu       (158.121.104.33) in ./pub/tex/.     dvitops - by James Clark. Available via anonymous ftp from any CTAN site       (see question 22, e.g., pip.shsu.edu (192.92.115.10)), in       ./tex-archive/dviware/dvitops. Dvitops is written in C and will       compile under Unix, MSDOS, VMS, and Primos. 3) How can I include a PostScript figure in LaTeX?   In LaTeX2e, the best way is \usepackage[dvips]{graphics}.   Perhaps the best way to do this is to use the psfig macros written   by Trevor Darrell. They are available via anonymous ftp from   any CTAN site (see question 22) in graphics/psfig. You will   also need a dvi to PostScript conversion program that supports   \specials. The ones mentioned in question 2 do, and come with a   version of psfig ready to use with them. The psfig macros work best   with Encapsulated PostScript Files (EPS). In particular, psfig will   need the file to have a BoundingBox (see Appendix C of the   _PostScript Language Reference Manual_). If you don't have an EPS   file, life can be difficult.   To allow resizing by dvips (see question 2) with PostScript files   that are not EPS files, add the one line comment   %%BoundingBox: llx lly urx ury"   prior to any non-comment line in the PostScript file. The four   ``lower left'' and ``upper right'' arguments must be numbers to   indicate the lower left and upper right corner in units of 1/72 of   an inch. Otherwise, dvips assumes the PostScript file fills a whole   page.   One further note about including PostScript figures is that they   are not part of the dvi file, but are included when you use a dvi   to PostScript conversion program. As a result, most dvi previewers   will simply show the blank space TeX has reserved for your figure,   not the figure itself. LaTeX2e (see question 41) will have a standard   interface for graphics inclusion, rotation, color, and other   driver-related features.   Anil K. Goel has written a long document describing in detail how to   include figures, pictures, and images in LaTeX documents. It is available   via anonymous ftp from math.uwaterloo.ca (129.97.140.144) in   ./pub/figsInLatex.ps.Z. A dvi file with the included PostScript files   is also available. 4) Where can I find a DVI previewer for machine Y running Q?   This briefly lists some previewers available via anonymous ftp. All   are available from any CTAN site (see question 22) in addition to the   sites listed below:      dvipage - For SunView. This was published in volume 15 of        comp.sources.unix and is available at sites that archive        this. One such source is archive.cis.ohio-state.edu        (128.146.8.52).      xtex - For the X Window System. Available via anonymous ftp        from ftp.cs.colorado.edu (128.138.243.151) in        ./pub/cs/misc/SeeTeX/SeeTeX/SeeTeX-*.tar.Z.      dviapollo- for Apollo Domain. Available via anonymous ftp from        labrea.stanford.edu (36.8.0.112) in ./pub/dviapollo.tar.Z.      dvidis - For VAXstation VWS. Available via anonymous ftp from        src.doc.ic.ac.uk (146.169.2.1) in /packages/tex/dviware/dvidis.      xdvi - Also for the X Window System. Available via anonymous ftp        from ftp.x.org (192.112.44.100) in ./contrib/xdvi.tar.Z. Karl        Berry has a version of called xdvik with features analogous        to his dvipsk (see question 2) available via anonymous ftp from        ftp.cs.umb.edu (158.121.104.33) in ./pub/tex.      dvitovdu - for Tektronix 4010 and other terminals under Unix.        Available via anonymous ftp from any CTAN site (see question 22)        in the directory ./dviware/dvitovdu.      dvi2tty - A dvi to ASCII conversion program, for normal terminals.        Available from ftp.cs.ruu.nl (131.211.80.17) in        ./pub/TEX/DVI/dvi2tty.shar. A VMS version is available from        [email protected] (see question 22).      texsgi - For SGI under Irix. Available via anonymous ftp from        ftp.brl.mil (128.63.16.158) in ./info-iris/tex. Both a binary        and source are available, but be sure to get the fonts as well.   5) Where can I get the manual for PiCTeX?   The PiCTeX manual is not free. It is available for $30 ($35 with the   disk) from the TeX Users Group:                     TeX Users Group                     P. O. Box 869                     Santa Barbara, CA 93102-0869 (USA)                     805-963-1338                     FAX: 805-963-8358                     [email protected]   The proceeds from this sale go to Michael Wichura, the author of PiCTeX,   and TUG. 6) In LaTeX, I put some definitions in my document, but I get the error   ``Use of \@ doesn't match its definition'' or ``You can't use   \spacefactor in vertical (or math) mode.'' What's wrong?   Definitions should be be in a style file, and if you move them there,   you should have no problem.   If you don't want to do that, you need to include \makeatletter   before the definitions to allow the ``internal'' LaTeX commands to   be accessed.  These commands are normally protected from change by   having @ in them.  Since @ is not a letter, it is normally not   allowed as part of a multi-letter command name. To access internal   commands you need to tell LaTeX to pretend that @ is a letter.   This happens automatically when LaTeX reads a style file, but in   your main document you need to surround the offending commands with   \makeatletter ... \makeatother. 7) What is OzTeX and where can I get it (TeX for the Mac)?   OzTeX is a version of TeX for the Macintosh. An older version of   OzTeX (1.42) is public domain, but newer versions are shareware. A   DVI Previewer and PostScript driver are also included. It should   run on any Macintosh Plus, SE, II, or newer model, but will not   work on a 128K or 512K Mac. It was written by Andrew Trevorrow, and   is available via anonymous ftp from from midway.uchicago.edu   (128.135.12.73) in ./pub/OzTeX, which contains other public domain   TeX-related software for the Mac as well, or on a floppy disk from   TUG (see question 11).  Questions about OzTeX may be directed to   [email protected].   8) What is Fig and where can I get it?   Fig is a menu driven tool similar to MacDraw that allows you to   draw objects on the screen of a Sun Workstation running SunView.   TransFig is a set of tools which translate the code fig produces to   other graphics languages including PostScript and the LaTeX picture   environment. Both are available via anonymous ftp from   ftp.cs.cornell.edu (128.84.218.75) in ./pub/fig. Both Fig and   TransFig are also available from the Clarkson archive server at   sun.soe.clarkson.edu (see question 22). Fig is supported by Micah   Beck ([email protected]) and Transfig is maintained by Brian   Smith ([email protected]). Another tool for fig conversion is fig2MF   which generates METAFONT code from fig input. It is available from   the CTAN archives discussed in question 22.   XFig is essentially the same program except it runs under the X   Window System. It is available via anonymous ftp from ftp.x.org   (192.112.44.100) in ./contrib/applications/drawing_tools/xfig. It   was written by Brian Smith. 9) How do I get WEB for C, FORTRAN, or some other language?   TeX is written in the programming language WEB; WEB is a tool to   implement the concept of ``literate programming.'' For more information   on literate programming, see the newsgroup comp.programming.literate.   There is a version of WEB for C called CWEB written by Silvio Levy. It   is available via anonymous ftp from princeton.edu (128.112.128.1) in   the directory ./pub/cweb.   There is a version of WEB called Spidery WEB which supports many   languages including ADA, awk, and C. It was written by Norman Ramsey   and, while not in the public domain, is usable free. It is available   via anonymous ftp from pip.shsu.edu (192.92.115.10) in   tex-archive/web/spiderweb.   FWEB is a version of WEB for Fortran, Ratfor, and C written by John   Krommes ([email protected]). Version 1.13 is available via   anonymous ftp from lyman.pppl.gov (192.55.106.129) in ./pub/fweb.   SchemeWEB is a Unix filter that translates SchemeWEB into LaTeX source   or Scheme source. It was written by John Ramsdell and is available from   sun.soe.clarkson.edu (128.153.12.3) in ./pub/tex/tex-programs/schemeweb.   APLWEB is a version of WEB for APL and is available from   watserv1.waterloo.edu (129.97.129.140) in ./languages/apl.   There are three flavors of WEB that are language-independent and   have substantial user communities: funnelweb, noweb, and nuweb.   NoWeb and NuWeb both emphasize simplicity; NoWeb is a bit simpler   and more flexible, but NuWeb is more portable and easier to   install.  FunnelWeb is more complex, but is routinely used on a   wide variety of machines.  All three systems are available from any   CTAN site (see question 22) in directory   /tex-archive/web/{funnelweb,noweb,nuweb}.  An introduction to NoWeb   appeared in the September 1994 IEEE Software, page 97.  Funnelweb   also appeared in comp.sources.unix volume 26 issue 121, posted 11   April 1993.   Most of the above are also available from your nearest CTAN site   (see question 22). 10) How can I typeset music in TeX?    A package called MuTeX, written by Andrea Steinbach and Angelika    Schofer, aids in doing this. It is available via anonymous ftp    from ftp.cs.ruu.nl (131.211.80.17) in pub/TEX/MuTeX.tar.Z.  This    package allows you to typeset single-staff music and lyrics.    A more powerful package which allows the typesetting of orchestral    and polyphonic music is MusicTeX, written by Daniel Taupin    ([email protected]). It is available via anonymous ftp from    rsovax.ups.circe.fr (130.84.128.100) [.musictex]. It should also    be available from the archive sites detailed in question 22.    There is a mailing list for discussion of typesetting music in TeX.    To subscribe, send a request to [email protected]. 11) What is TUG and TUGboat?    TUG is the TeX Users Group. TUGboat is their newsletter, containing    useful articles about TeX and METAFONT. TUG also distributes    TeX-related microcomputer software on disks. Inquiries should be    directed to:                     TeX Users Group                     P. O. Box 869                     Santa Barbara, CA 93102-0869 (USA)                     805-963-1338                     FAX: 805-963-8358                     [email protected] 12) How do I convert Adobe's afm files to tfm format?    An afm2tfm program is distributed with dvips, available via    anonymous ftp from labrea.stanford.edu (36.8.0.112) in ./pub. Alan    Jeffrey's fontinst package is an afm2tfm converter written in TeX    and will be used to support the PostScript tfm files for LaTeX2e    (see question 41). It is available from any CTAN site (see question    22).    For the Macintosh, there is a program called EdMetrics which does    the job (and more). It is available free from:              Blue Sky Research              534 Southwest Third Avenue              Portland, Oregon 97204 (USA)              800-622-8398 or 503-222-9571 13) In LaTeX, how do I get a double-spaced document?    Are you producing a thesis, and trying to obey regulations that were    drafted in the typewriter era?  LaTeX is a typesetting system, so the    appropriate design conventions are for ``real books''.  Find whoever    is responsible for the regulations, and try to get the wording changed    to cater for typeset theses (e.g., to say ``if using a typesetting    system, aim to make your thesis look like a well-designed book'').    If you fail to convince your officials, or want some inter-line    space for copy-editing:     - In LaTeX2e, use \linespread. For double-spaced output, use       \linespread{1.6}.     - Try changing \baselinestretch: \renewcommand{\baselinestretch}{1.2}       may be enough to give officials the impression you've kept       to their regulations.  Don't try changing \baselineskip: its       value is reset at any size-changing command.     - Alternatively, get doublespace.sty from any CTAN site (see question 22,       e.g., pip.shsu.edu (192.92.115.10)) in       ./tex-archive/macros/latex/contrib/misc. There's also a setspace.sty       in the same directory which is more flexible, and consistent with the       latest release of LaTeX.    It's not worth going to a lot of trouble.  (If officials won't allow    standard typographic conventions, you won't be able to produce an    aesthetically pleasing document anyway!) 14) In LaTeX, how do I include a file in the verbatim environment?    A good way to do this is to use Rainer Sch\"opf's verbatim.sty,    which provides the command \verbatiminput that takes a file    as an argument. This package is available from any CTAN site (see    question 22) in ./tex-archive/macros/latex/distribs. Several    files are needed.    Another way to do this is to use the alltt environment defined in    the style file alltt.sty available from the CTAN archives in    ./tex-archive/macros/latex/contrib/misc/alltt.sty. 15) In LaTeX, how do I do Y?    If you can't figure out how to do something in LaTeX after you    have read the manual very carefully, asked your local LaTeX    guru, and thought about it, there is a LaTeX help service    available. Please note that the way to accomplish something    in LaTeX is often by using an appropriate style file, so please    check this also (see question 16). If none of this works, send mail    in English describing your problem to [email protected].    If you haven't gotten a reply to your problem within about a week,    send mail to [email protected]. 16) Where can I find a TeX macro or LaTeX style file for doing Y?    Before you ask for a TeX macro or LaTeX style file to do something,    please search the TeX macro index written by David M. Jones    ([email protected]) and available via anonymous ftp    from theory.lcs.mit.edu (18.52.0.92) in ./pub/tex/TeX-index. Those    without access to anonymous ftp can send a message containing the    line ``send tex TeX-index'' to [email protected].    The index is an excellent reference document with plenty of    cross-references. Also, many of the archive sites mentioned in    question 22 maintain extensive latex style collections, which you    can look through if you need something not in the index.    Another possibility is to use the searching features of the CTAN    archives (see question 22). Once you have an anonymous ftp connection    established to a CTAN site, you can type the command `quote site index    <term>' and it will provide a list of files with the string <term> in    their names.     17) How do I generate an index in TeX/LaTeX?    Making an index is not trivial. There are several indexing programs    which aid in doing this. The following are available from any CTAN    site (see question 22):      makeindex - for LaTeX under Unix (but runs under other OS's         without changes). A version for the Macintosh is available from         Johnny Tolliver at tolliver%[email protected]. The         Makeindex documentation is a good source of information on how         to create your own index. Makeindex can be used with some TeX macro         packages other than LaTeX, such as Eplain.      idxtex - for LaTeX under VMS.      texix - for TeX on CMS and Macintosh machines.      texindex - for LaTeX under Unix. Available from         comp.sources.misc archives in Volume 23. 18) How do I get METAFONT to do what I want it to do?    METAFONT allows you to create your own fonts, and ordinary TeX users    will never need to use it. METAFONT, unlike TeX, requires some    customization. Each output device for which you will be generating    fonts needs a mode associated with it. Modes are defined using the    mode_def convention described on page 94 of _The METAFONTbook_. So    first create a file, which we will call local.mf, containing all the    mode_defs you will be using. The file modes.mf by Karl Berry,    available via anonymous ftp from ftp.cs.umb.edu (158.121.104.33) in    ./pub/tex is a good starting point for this. Listings of settings for    various output devices are also published periodically in TUGboat    (see question 11). Now create a plain base file using inimf, plain.mf,    and local.mf:       % inimf       This is METAFONT....       **plain                 # you type plain       (output)       *input local            # you type this       (output)       *dump                   # you type this       Beginning to dump on file plain....       (output)       %    This should create a base file named plain.base (or something close)    and should be moved to the directory containing the base files on    your system.    Now you need to make sure METAFONT loads this base when it starts    up. If METAFONT loads the plain base by default on your system, then    you're ready to go. Under Unix, we might, for instance define a    command mf which executes ``virmf &plain,'' loading the plain base    file.    The usual way to create a font with plain METAFONT is to then start    it with the line       \mode=<mode name>; mag=<magnification>; input <font file name>    in response to the * prompt or on the METAFONT command line. If    <mode name> is unknown or omitted, then the mode defaults to proof    mode. If this has happened METAFONT will produce an output file    called <font file name>.2602gf. The <magnification> is a floating    point number or magstep (magsteps are defined in _The METAFONTbook_    and _The TeXbook_). If mag=<magnification> is omitted, then the    default is 1. For example, to generate cmr10 at 12pt for an epson    printer you would type       mf \mode=epson; mag=1.2; input cmr10    Note that under Unix the '\' and ';' characters must usually be    escaped, so this would typically look something like       mf \\mode=epson\; mag=1.2\; input cmr10    If you don't have inimf or need a special mode that isn't in the    base, you can put its commands in a file (e.g., ln03.mf) and invoke    it on the fly with the \smode command. For example, to create    ln03.300gf for an LN03 printer, using the file      % This is ln03.mf as of 2/27/90        % mode_def courtesy of John Sauter     proofing:=0;   fontmaking:=1; tracingtitles:=0;      pixels_per_inch:=300;  blacker:=0.65; fillin:=-0.1;  o_correction:=.5;    (note the absence of the mode_def and enddef commands), you would type       mf \smode="ln03"; input cmr10     19) Where do I get TeX/LaTeX for machine Y running Q?    Unix - The Unix TeX distribution is available via anonymous ftp from any       CTAN archive (see question 22). The Northwest Computing Support Center       was ordered closed by the University of Washington, thus Unix TeX       can no longer be ordered.       Instructions for retrieving TeX via anonymous ftp are available       in the document FTP.nwc, itself available via anonymous ftp from       ftp.cs.umb.edu (158.21.104.33) in ./pub/tex.       Note: The Unix version of TeX allows your ``macros'' or ``inputs''       and ``fonts'' directories to be hierarchically organized with       further subdirectories, rather than dumping everything into one       directory. This can cause TeX to start very slowly. The cure       for this problem is to insure each subdirectory contains either       only directories or only files.    AIX - TeX for the IBM RS6000 running AIX can be found on       ftp.dante.de (129.206.100.192) in ./tex-archive/systems/unix/aix3.2.    386/ix - Executables for the 386/ix are available via anonymous ftp       from tik.vtt.fi (130.188.52.2) in ./pub/tex/bin-386ix and from       math.berkeley.edu (128.32.183.94) in ./pub/tex386ix.tar.Z.    PC - A TeX package for the PC, including LaTeX, BibTeX, previewers,       and drivers is available via anonymous ftp from       vax.eedsp.gatech.edu (130.207.226.24) in ./pub/TeX. The variety here       is sbtex version 30 by Wayne Sullivan. EmTeX, another TeX package       for the PC by Eberhard Mattes, is available via anonymous ftp from       ftp.dante.de (129.206.100.192) in       ./tex-archive/systems/msdos/emtex and also from niord.shsu.edu       (192.92.115.8) in [.emtex]. This package includes LaTeX, METAFONT,       BibTeX, etc., as well. Documentation is available in both German       and English.    Mac - see question 7 for a public domain version (OzTeX). Another version       is CMacTeX, which has TeX 3.14, METAFONT 2.7, a screen previewer,       dvips, a PostScript printing utility for the LaserWriter, and some font       managing utilities. It is available from the CTAN archives discussed       in question 22.    TOPS-20 - TeX was originally written on a DEC-10 under WAITS, and so       was easily ported to TOPS-20. A Distribution that runs on TOPS-20       is available via anonymous ftp from ftp.math.utah.edu       (128.110.198.34) in ./pub/tex/pub/web.    VAX/VMS - TeX for VMS is available from any CTAN site (see question 22)       in the directory ./systems/vms. Standard tape distribution is       through DECUS.    Atari - TeX is available for the Atari ST from atari.archive.umich.edu       (141.211.165.41) in ./atari/tex. If anonymous ftp is not available       to you, send a message containing the line ``help'' to       [email protected]. The mail server can uuencode       binary files. Another version can be obtained via anonymous       ftp from ifi.informatik.uni-stuttgart.de (129.69.211.1) in       ./pub/atari.st/tex. There is also lots of TeX stuff for the       Atari on the CTAN and ftp.cs.ruu.nl archives mentioned in       question 22.    Amiga - A full implementation of TeX 3.1 call PasTeX and METAFONT 2.7        are available via anonymous ftp from merlin.etsu.edu (192.43.199.20)        in ./ab20/AMIGA. It is also available via anonymous ftp from        forwiss.uni-passau.de (132.231.20.10) in ./pub/amiga/tex.        You can also order a CDROM containing this and other amiga software        from Walnut Creek CDROM, (510) 947-5997.    Tandy 6000 - If you are interested in building TeX on this machine        contact Ken Yap ([email protected]), and he'll help you. 20) Where can I get a thesis style for LaTeX?    Thesis styles are usually very specific to your University, so it's    usually not profitable to ask the whole newsgroup for one. If you    want to write your own, a good place to start is the ucthesis style    available from any CTAN archive in macros/latex/contrib/ucthesis    (see question 22). 21) How do I get symbols for ``the real numbers'', ``the complex numbers'',    and so on?    These symbols are known as ``blackboard bold'' and are available    in the AMS fonts ``msam'' (e.g., ``msam10'' for 10pt) and    ``msbm''.  They replace the older ``msxm'' and ``msym''. The fonts    have a large number of mathematical symbols to supplement the ones    provided by TeX. The fonts are available via anonymous ftp from    e-math.ams.com (130.44.1.100) in the directory ./ams/amsfonts.    Two files which load the fonts and define the symbols are    provided, and both work with either TeX or LaTeX. Questions or    suggestions regarding these fonts should be directed to    [email protected].    A geometric sans serif blackboard bold font by Alan Jeffrey is    available from any CTAN archive (see question 22) in    ./tex-archive/fonts/bbold.  Another set of blackboard bold fonts    which may fit better with computer modern fonts are the BBM* fonts    available from any CTAN site (see question 22) in    ./tex-archive/fonts/cm/bbm.    A set of LaTeX macros for a ``lazy person's'' blackboard bold are:       \newcommand{\R}{{\sf R\hspace*{-0.9ex}\rule{0.15ex}%       {1.5ex}\hspace*{0.9ex}}}       \newcommand{\N}{{\sf N\hspace*{-1.0ex}\rule{0.15ex}%       {1.3ex}\hspace*{1.0ex}}}       \newcommand{\Q}{{\sf Q\hspace*{-1.1ex}\rule{0.15ex}%       {1.5ex}\hspace*{1.1ex}}}       \newcommand{\C}{{\sf C\hspace*{-0.9ex}\rule{0.15ex}%       {1.3ex}\hspace*{0.9ex}}} 22) What repositories of TeX material are available, and how can I access    them?    To aid the archiving and retrieval of of TeX-related files, a TUG    working group developed the Comprehensive TeX Archive Network    (CTAN).  Each CTAN site has identical material, and maintains    authoritative versions of its material.  These collections are    extensive; in particular, almost everything mentioned in this    document is archived at the CTAN sites, even if not explicitly    stated.    The CTAN sites are currently ftp.dante.de (129.206.100.192)    ftp.tex.ac.uk (134.151.44.19), and pip.shsu.edu (192.92.115.10).    The organization of TeX files on all these sites is identical and    starts at ./tex-archive. To reduce network load, please use the    CTAN site or mirror closest to you. A complete and current list    of CTAN sites and mirrors can be obtained by using the finger    utility to finger [email protected].    To find software at a CTAN site, use anonymous ftp to the host,    and then execute the command `quote site index <search-term>'.    An extremely nice interface to CTAN is provided by the CTAN-Web Home    Page maintained by Norman Walsh ([email protected]). It is found at    http://jasper.ora.com/ctan.html. If your network connection to this    host is fast enough, it should be the method of choice for accessing    the archive.    The mail servers of the CTAN sites are not yet identical, but this is    planned. Here are the current methods of access via electronic mail:      - For the UK site, send a message to [email protected]. The        first non-blank line of the message must contain a valid        TeXserver command (help, directory, files, whereis, search,        or path). The program will then mail you a response notifying        you that your request has been received. If you fail to get a        response from the TeXserver, you may need to use the ``path''        command to help the program out. For Internet users the        return address is of the form name%site@nsfnet-relay, while        for Bitnet and EARN it is name%site@earn-relay (i.e., include        a line that says ``path name%site@nsfnet-relay'' along with a        line containing ``help'').      - For ftp.dante.de, send a message containing the line        ``help'' to [email protected].      - For the SHSU site, send a message with the line "help" to        [email protected]. This provides an ftp-like interface        through mail.    There are several other repositories of TeX material available:      - ftp.cs.ruu.nl (131.211.80.17) also contains a substantial TeX        archive with ftp access. To use it via email, send a message        containing the line ``help'' to [email protected]. This mail        server can send binary files in a variety of different formats.      - There are LISTSERV facilities for TeX at [email protected].        Send a message containing the line ``help'' to this address.      - For users on BITNET, access to anonymous ftp for some files can        be obtained indirectly by sending mail to [email protected].        Send a message containing the line ``help'' to this address for        more information.        There is also the DECUS TeX collection, a collection of TeX material    for VMS, Unix, MS-DOS, and the Macintosh. It is available via    anonymous ftp from wuarchive.wustl.edu (128.252.135.4) in ./decus/tex.    It can also be obtained from the DECUS Library (reference number    VS0058) in the US, or through your DECUS office outside of the US. To    contact the DECUS Library, send mail or call:                 The DECUS Program Library                 334 South Street SHR3-1/T25                 Shrewsbury, MA 01545-4195                 (800)332-3755    The last update to this collection was in February 1991, so it is old.        Another good source of information is NETWORK SOURCES OF TeX WARE by    Peter Flynn which appeared in TeXhax, volume 90, issues 45-47 (in    May 1990).       23) How do I use PostScript fonts with LaTeX?    The best way to do this is to install LaTeX2e (see question 41)    and use the PSNFSS2e package written by Sebastian Rahtz. It is    available from all the major archives mentioned in question    22. Other methods for using PostScript fonts in LaTeX are    cumbersome at best. 24) How can I convert from format Y to TeX or LaTeX, and vice-versa?    troff - troff-to-latex is available from any CTAN site (see      question 22) in the directory ./support/troff-to-latex. This      program, written by Kamal Al-Yahya at Stanford, assists in the      translation of a troff document into LaTeX format. It recognizes      most -ms and -man macros, plus most eqn and some tbl      preprocessor commands. Anything fancier needs to be done by      hand. Two style files are provided. There is also a man page      (which converts very well to LaTeX :-). The program is      copyrighted but free. An enhanced version of this program,      tr2latex, is available from ftp.informatik.rwth-aachen.de      (137.226.112.172) in ./pub/TeX.  The DECUS TeX distribution (see      question 22) also contains a program which converts troff to      TeX. If you are interested in obtaining a copy of this program      without getting the entire DECUS TeX distribution, send the      command: SENDME TROFFTOTEX in the body of a mail message to      [email protected] ([email protected]), or use anonymous ftp      to the directory [.TROFFTOTEX] on Niord.SHSU.edu (192.92.115.8).    scribe - Mark James has a copy of scribe2latex he has been      unable to test but which he will let anyone interested have.      Send email to [email protected]. The program was written      by Van Jacobson of Lawrence Berkeley Laboratory.    wordperfect -  wp2latex is available on wuarchive.wustl.edu      (128.252.135.4) in the directory ./mirrors/msdos/tex and from      any CTAN site (see question 22) in ./support/wp2latex. This is      a PC program written in Turbo Pascal by R. C. Houtepen at the      Eindhoven University in the Netherlands. It converts      WordPerfect 5.0 documents to LaTeX. Pascal source is included.      Users find it ``helpful'' and ``decent'' in spite of some      limitations. It gets high marks for handling font changes.      Limitations include no indices, table of contents, margins or      graphics.  It also won't handle the new features of WordPerfect      5.1, in particular the equation formatter. The program is      copyrighted but free.      Glenn Geers of the University of Sydney([email protected])      is translating wp2latex into C and adding some WordPerfect 5.1      features, in particular its equation handling. This is an      ongoing project; the most recent version can be retrieved via      anonymous ftp from suphys.physics.su.oz.au (129.78.129.1) in      ./wp2latex. It was posted to alt.sources on 8 August 1990.      Commercial packages are available for DOS which convert from      WordPerfect to LaTeX, and from TeX and LaTeX to WordPerfect, but      I am unaware of any free products which do this.    PC-Write - pcwritex.arc is available on wuarchive.wustl.edu      (128.252.135.4) in directory mirrors/msdos/tex and in zoo format      from any CTAN site (see question 22) in ./support/pcwritex.      This is a print driver for PC-Write that ``prints'' a PC-Write      V2.71 document to a TeX-compatible disk file. It was written by      Peter Flynn at University College, Cork, Ireland. It is public      domain.    runoff - Peter Vanroose ([email protected]) has      written a RUNOFF-to-TeX conversion program in VMS Pascal.  It is      available from comp.text archives (they do exist, don't they?  The      program was submitted in December 1987) or from the author      ([email protected]) or from Mark James ([email protected]).    refer/Tib - There are a few programs for converting bibliographic data      between BibTeX and refer/Tib formats.  They are available via      anonymous ftp from ftp.ai.mit.edu (128.52.32.11) in the      directory ./pub/refer-to-bibtex.  In spite of the directory name,      it also contains a  shell script to convert BibTeX to REFER as      well. Unfortunately, this collection is not maintained.    RTF - A program for converting Microsoft's Rich Text Format to TeX      is available via anonymous ftp from astro.princeton.edu      (128.112.128.131) in ./pub/rtf2TeX.tar.Z. It was written and is      maintained by Robert Lupton ([email protected]). There is      also an rtf2LateX written by Erwin Wechtl available from      ftp.vmars.tuwien.ac.at (128.130.39.16) in ./pub/misc.    Microsoft Word - A rudimentary program for converting MS-Word      to LaTeX is wd2latex, for MS-DOS, available via anonymous ftp      from any CTAN site (see question 22). A better idea, however,      is to convert the document to RTF format and use the RTF      converter mentioned above.        In addition, a group at Ohio State University is working on a common    document format based on SGML.  In theory any format could be    translated to or from this one.  Also, Framemaker supposedly has    ``import filters'' to aid in the translation from alien formats    (presumably including TeX) to Framemaker; perhaps other desktop    publishing programs have similar things.       25) How do I get a file into the major style repositories?        Use anonymous ftp to any CTAN archive (see question 22) and    retrieve the file README.uploads in the root directory. It contains    instructions for uploading files and notifying the appropriate    people for that site.    If you cannot use ftp, mail your contribution to [email protected]    and it will be passed along. You will make everyone's life easier    if you choose a descriptive and unique name for your submission, so    it's probably good idea to browse through some of the styles    already available to insure your style file's name is not already    in use. 26) Where can I get font Y?    A comprehensive list of METAFONT fonts is posted to Comp.fonts    about once every six weeks by Lee Quin ([email protected]). It contains    both commercial fonts and fonts available via anonymous ftp. Most    of the fonts available via anonymous ftp are available from    the CTAN archives (see question 22). Also, the file wujastyk.txh    ./tex-archive/digests/texhax/txh/wujastyk.txh is a copy of    Dominik Wujastyk's font article, and contains information on    METAFONT fonts as well. 27) Where can I get a dvi driver for the HP LaserJet?    PC - The emtex package mentioned in question 19 contains a driver for       the LaserJet, dvihplj.    Version 2.10 of the Beebe drivers support the LaserJet. These drivers    will compile under Unix, VMS, and on the Atari ST and DEC-20's. They    are available from ftp.math.utah.edu (128.110.198.34) in ./pub/tex/dvi. 28) TeX and LaTeX are hyphenating words weirdly. What can I do?    You have a version mismatch problem. The hyphenation algorithm changed    between version 2.9 and 3.0. If you are using TeX version 3.0 or    later, make sure you have plain.tex and lplain.tex files with a    version number of at least 3.0.    For those of you curious about the change, here's what happened:    in versions of TeX before 3.0 the hyphenation algorithm would not    break a word if the part before the break was not at least two    characters long, and the part after the break at least three    characters long. Starting with version 3.0 two integer parameters,    \lefthyphenmin and \righthyphenmin, control the length of these    fragments. These are set to 2 and 3, respectively, in the new    plain and lplain formats. They can be set to any value, of course,    but if \lefthyphenmin + \righthyphenmin is greater than 62, all    hyphenation is suppressed. 29) How can I convert a TeX or LaTeX file into a plain ASCII file,    with all the formatting intact, a la nroff?    Ralph Droms ([email protected]) has a style file and a C program    that provide the LaTeX equivalent of nroff. Although it doesn't do    a good job with tables and math, it's the best way to convert that    I've seen. The software is available for anonymous ftp from    sol.cs.bucknell.edu (134.82.1.8) in ./droms/txt-dist.tar. This is a    modification of the dvi2tty program; the original often does an    acceptable job and can be gotten from any CTAN site (see question 22).    Another possibility is to use screen.sty, available from all the    major archives. However you need a program called crudetype to    process the resulting dvi file. It is available from    emx.utexas.edu (128.83.186.11) in    ./pub/mnt/source/tex/tex-3.0/DVIware/lpr-viewers/crudetype and    from ftp.uni-stuttgart.de (129.69.8.13) in    ./tex-archive/dviware/screenview. Another possibility is to use    the LaTeX-to-ASCII conversion program, l2a, available from    comp.sources.misc archives (one archive site is ftp.uu.net    (192.48.96.9)), although this is really more of a de-TeXing    program. If you are running under Unix and have C++ and perl, you    might try Jonathan Monsarrat's LameTeX package (which actually    does much more than this), available from wilma.cs.brown.edu    (128.148.33.66) in ./pub/lametex.tar.Z. 30) How do I enlarge TeX? I keep getting `memory capacity exceeded'    errors.    Most of the time, a ``memory capacity exceeded'' error can be fixed    without enlarging TeX.  The most common causes are unmatched braces,    extra-long lines, and poorly-written macros.  Extra-long lines    are often introduced when files are transferred incorrectly between    operating systems.  (The tell-tale sign of an extra-long line error    is when the complaint is that the `buf_size' has overflowed.)    If you really need to extend your TeX's capacity, the proper method    varies depending on your installation.  In the purest form, you    change the parameters in module 11 (``The following parameters can    be changed...'')  In less pure forms, you might need to modify a    change file, or perhaps change some environment variables.  Consult    the documentation that came with your particular implementation. 31) In LaTeX, I used \pagestyle{empty}, but the first page is still    numbered. What do I do?    If you see this, you are using the \maketitle command too. This is    not a bug but a feature! The standard LaTeX styles are written so    that initial pages (pages containing a \maketitle, \part, or \chapter)    have a different page style than the rest of the document. Hence, the    above commands internally issue a \thispagestyle{plain}. This is    usually not acceptable behavior is the page style is `empty'.    Possible workarounds include:       - Put \thispagestyle{empty} immediately after the \maketitle command,       with no blank line between them.     - Use fancyheadings.sty, available from any CTAN (see question 22).       In this style, the style for initial pages can be customized as well. 32) Where do I find documentation about BibTeX?    BibTeX, a program originally designed to produce bibliographies in    conjunction with LaTeX, is explained in Section 4.3 and Appendix B    of Leslie Lamport's LaTeX manual.  The ``BibTeXing'' document,    contained in the file btxdoc.tex, gives a more complete description.    _The LaTeX Companion_ also has information on BibTeX and writing    BibTeX style files.    The ``Designing BibTeX Styles'' document, contained in the file    btxhak.tex, explains the postfix stack-based language used to    write BibTeX styles (.bst files).  The file btxbst.doc is the template    file for the four standard styles (plain, abbrv, alpha, unsrt). It    also contains the documentation for them.    The current Unix-BibTeX man page, contained in the file    bibtex.1, was updated in January 1992 and is about one page long.    There's an old and obsolete version floating around, written in 1985    before ``BibTeXing'' and ``Designing BibTeX Styles'' appeared, that is    several pages long.  You should ignore it (or throw it away), since it    describes BibTeX version 0.98, style files of which are incompatible    with the current version, 0.99 (to be precise, 0.99c).    All files mentioned in this answer are available via anonymous ftp    from labrea.stanford.edu (36.8.0.112) in the BibTeX ftp area,    tex/bibtex. All the non-Unix files should be available on any system    that runs BibTeX; if they're not on your system, please complain to    your BibTeX installer or to your distribution source. 33) How do I use BibTeX with plain TeX?    The file btxmac.tex contains TeX macros and documentation for using    BibTeX with plain TeX, either directly or with Karl Berry's Eplain    package. It is available via anonymous ftp from labrea.stanford.edu    (36.8.0.112) in tex/bibtex (see question 32 for more information    about BibTeX). 34) How do I draw Feynman diagrams in LaTeX?    Michael Levine's macro package for drawing Feynman diagrams in LaTeX    is available via mail-server from physics.utoronto.ca. Send a message    containing the line ``send INDEX'' to [email protected]    for information on how to retrieve it. It is also available from any    CTAN site or mirror (see question 22).    Jos Vermaseren's ``axodraw'' package, uses PostScript \specials    and is thus slightly less portable but much more powerful. Also,    there is Thorsten Ohl's ``feynmf'' package for LaTeX2e which uses    METAFONT (or MetaPost) to combine flexibility and portability.    Both are available from any CTAN site (see question 22). 35) What is the New Font Selection Scheme (NFSS)?    NFSS is an extension to LaTeX written by Frank Mittelbach and Rainer    Sch\"opf. It is described in TUGboat, volume 10 (1989), No. 2.    In traditional typesetting, fonts are described by four parameters:    the family (e.g., computer modern), the series (i.e., the weight and    width of the font, like light or bold), the shape (e.g., italic), and    the size. NFSS is a mechanism allowing the user to change any of these    independently. NFSS makes it relatively easy to use nonstandard fonts    such as the PostScript ones with LaTeX, and easy to change math fonts.    It also allows dynamic loading of fonts at runtime (not when the    format file is created).    NFSS is no longer supported for LaTeX version 2.09, but is standard    with LaTeX2e (see question 41).    There is one caveat that applies to LaTeX documents written for    the OLD scheme: some of them use special styles for special fonts    which will not work under the NFSS. 36) In LaTeX, my cross-references for floats (figures and tables) are    incorrect. What's wrong?    The \label command must come after the \caption command, or    be part of it. For example,       \begin{figure}               \begin{figure}       \caption{A Figure}    or     \caption{A Figure\label{fig}}       \label{fig}                  \end{figure}       \end{figure} 37) I want to change the margins in LaTeX. What can I do?    This answer first helps you change the margins throughout a    document, then tells you how to change the margins in a portion    of the document.    Perhaps the easiest way to get more out of a page in LaTeX is to    get fullpage.sty, available from all the major archive servers    mentioned in question 22. This sets the margins of the page identical    to those of Plain TeX, i.e., 1-inch margins at all four sides of the    paper. It also contains an adjustment for A4 paper.    Here is a brief explanation of what's going on with the page    parameters in LaTeX. They are explained in section C.4.2 of the    LaTeX manual (p. 163). The margin parameters represent measurements    made to the DVI file. The origin in DVI coordinates is one inch    from the top of the paper and one inch from the left side. This    explains the ``one inch less than'' terminology used in the LaTeX    manual. In DVI coordinates, positive horizontal measurements extend    right across the page, and positive vertical measurements extend down    the page. Thus, for margins closer to the left and top edges of the    page than 1 inch, the corresponding parameters, e.g.,    \evensidemargin, \oddsidemargin, \topmargin, can be set to negative    values.    Finally, to change the margins of a document within the document,    modifying the parameters listed on page 163 will not work. They    can only be changed in the preamble of the document, i.e, before    the \begin{document} statement. To adjust the margins within a    document we define an environment which does it:      \newenvironment{changemargin}[2]{\begin{list}{}{         \setlength{\topsep}{0pt}\setlength{\leftmargin}{0pt}         \setlength{\rightmargin}{0pt}         \setlength{\listparindent}{\parindent}         \setlength{\itemindent}{\parindent}         \setlength{\parsep}{0pt plus 1pt}         \addtolength{\leftmargin}{#1}\addtolength{\rightmargin}{#2}         }\item }{\end{list}}    This environment takes two arguments, and will indent the left    and right margins by their values, respectively. Negative values    will cause the margins to be widened, so    \begin{changemargin}{-1cm}{-1cm} widens the left and right margins    by 1cm. 38) How do I find the width of a letter, word, or phrase in TeX?    Put the word in a box, and measure the width of the box. For example,        \setbox0=\hbox{hi}        width=\wd0    Note that if the quantity in the hbox is a phrase, the actual    measurement only approximates this width, since the interword glue    can be adjusted in paragraph mode.    In LaTeX, the following works (taken from the manual):        \newlength{\gnat}        \settowidth{\gnat}{\em small}    This sets the value of the length command \gnat to the width of ``small''    in emphasized text. 39) In LaTeX, is there a comment or ``ignore'' environment with which    I can exclude blocks of text from the .dvi file?    Rainer Sch\"opf's verbatim.sty provides a comment environment which    excludes everything between \begin{comment} and \end{comment}. It is    available via anonymous ftp from any CTAN site (see question 22) in    ./tex-archive/macros/latex/distribs. Several files are needed to    install the package. A more general environment for doing this is    comment.sty, also available from the CTAN sites in    ./tex-archive/macros/latex/contrib/misc. 40) Where can I find a spelling checker for my TeX file?    For Unix, ispell is probably the program of choice. It is available    from any CTAN site (see question 22) in ./tex-archive/support/ispell.    For DOS, jspell is an extended version of ispell, and is available via    anonymous ftp from oak.oakland.edu (141.210.10.117) in    ./pub/msdos/tex/jspell*.zip.    For VMS, a spell checker can be found via anonymous ftp from ftp.spc.edu    in  [.MACRO32.SAVESETS]. Retrieve SPELL.ZIP and SPELL_DICTIONARY.ZIP.    For the Macintosh, a very nice spell checker called Excalibur is    available from any CTAN site (see question 22) in    ./tex-archive/support/mac/excalibur. 41) What is LaTeX2e?    LaTeX2e is the new standard version of LaTeX, prepared and    supported by the LaTeX3 project team. It is the current version of    LaTeX and is available from any CTAN site (see question 22) in    ./tex-archive/macros/latex. LaTeX 2.09 is no longer supported.    LaTeX2e is upwardly compatible with LaTeX 2.09, but supports many new    features, including:     - NFSS (see question 35) is now standard.     - SliTeX is consolidated into it, and there is no longer a need for       a separate program.     - The output routine gives better control of floating environments,       such as figures.     - There is a documented interface to style files.     - Enhanced box commands, e.g., options to specify the height of a       minipage.     - \ref is now robust and can be used in \caption.     - \newcommand can define commands with optional arguments.     - A standard package for color and graphics inclusion.    Since LaTeX2e is supported, you can report bugs or problems with it by    typing `latex latexbug' and sending the report it generates to    [email protected]. 42) In LaTeX, how can I define a new log-like function?    Use the \mathop command, as in:         \newcommand{\diag}{\mathop{\mathrm{diag}}}    Subscripts and superscripts to \diag will be done identically to \lim.    If you want your subscripts and superscripts placed to the right, do:         \newcommand{\diag}{\mathop{\mathrm{diag}}\nolimits}    Older versions of LaTeX may not define \mathrm; alternatively, use    {\rm diag}. 43) In LaTeX, how do I put a \sqrt in my \caption statement?    \sqrt is a fragile command and the argument to \caption is ordinarily    a moving argument. Therefore \sqrt needs to be preceded with a \protect    command. 44) In LaTeX, how do I get thin and thick \hlines in a table?    In the preamble, do:         \setlength{\doublerulesep}{\arrayrulewidth}.    Then in a table or array, do:         <stuff in the table>  \\\hline         %thin hline         <more stuff in table> \\\hline\hline   %thick hline 45) In LaTeX, how do I number the bibliography using Arabic numbers without    square brackets or using superscripts?    In a style file (or between \makeatletter ... \makeatother, see    question 6), put:         \renewcommand\@biblabel[1]{#1.}     % Arabic numbers, no brackets         \renewcommand\@biblabel[1]{$^{#1}$} % Superscripts 46) In LaTeX, why are my cites all numbered zero?    Your document style and your version of LaTeX are incompatible.    Since this may reflect an incomplete update done at some point,    you should probably get the complete distribution (see question    22).    This problem usually occurs using an old university style file    which is not maintained. If you are going to correct the style    file, the definition of \thebibliography needs to be updated from    article.cls (or article.sty). 47) In LaTeX, my figures get put on a page by themselves with too much    whitespace, but when I tried \begin{figure}[t] they get printed at    the end. Why?    Your figures are bigger than \floatpagefraction, but you are    willing to accept pages with less text than the default.  Use:         \renewcommand\floatpagefraction{.9}         \renewcommand\topfraction{.9}         \renewcommand\bottomfraction{.9}         \renewcommand\textfraction{.1}    You can adjust the cut-off value if you like, but it makes no    sense to go higher than .95 (LaTeX's default value is only .5).    Also, the first 3 values should be equal, and the last should be    1 - \floatpagefraction.  Otherwise, you are likely to get floats    flushed to the end. 48) In LaTeX, how do I make a line break in a section title?    It is better to try to prevent bad breaks by using ~ than to force    good breaks. Unfortunately, LaTeX's default styles make titles with    flush margins and most other styles have followed, so this may not    work in many cases. You should definitely avoid hyphenation in titles.    To force line breaks in a title, but not in the table of contents,    use the optional argument for \section:         \section[This is the Title]{This is\\ the Title}    One benefit of this is that \\ is safe and no \protect is needed. 49) In LaTeX, how do I number equations by section?    In a style file (or between \makeatletter ... \makeatother, see    question 6), put:         \renewcommand\theequation{\thesection.\arabic{equation}}         \@addtoreset{equation}{section}    If you have chapters with a preamble that comes before the first    section, you should not put equations there, as you will get funny    numbers like 3.0.1. There are also two style files available from    any CTAN site called seceqn.sty and apeqnum.sty. The first numbers    equations by section, and the second gives individual equation    numbers to equations in the appendix. -- Bobby Bodenheimer                           @hot.caltech.edu // ARPA  : [email protected]                | // BITNET: [email protected]                 | Woof! // UUCP  : {amdahl,ames!elroy}!cit-vax!bobby    |
