Of Significance. Don't miss universal TYPE command, one that "types" plain
text, squeezed, crunched, and library files. Command is created with ZFILER
calling LT, VTYPE, and a three-alias ALIAS.CMD suite. It's described at end
of Z-User's Corner below. Power of such command separates Z-System from other
operating systems.
P.J. Plauger, of C language and software tools fame, writes much needed
business ethics article in Computer Language, Sept., '87 issue, pages 13-19.
"Just because they can get away with it doesn't make it right." "Just because
you're right doesn't mean they can't get away with it." "Just because you can
get away with it doesn't make it right." "Just because they're right doesn't
mean you can't get away with it." Four seeming contradictions, much like
"right of might" versus "might of Right" of Z-News 309, top of page 3, and Of
Angels and Eagles of 704. P.J. starts slow but builds to a crescendo, tells
it like it must be for personal growth. Required reading!

From The Mail Box. George Dremann writes asking our help to establish commu-
nications with those who own Ithaca Intersystems S-100 computers, "especially
6MHz III Main Processor Boards." Are there enough of you left out there with
the soul to remember what S-100 is?) Since the company is no longer in busi-
ness present users should, may like to know who remains in their community.
If interested in becoming part of the community, please contact Mr. Dremann at

From Orinda, CA, Richard Wood considers buying a DT42 (Z-News 501), sends
us some benchmarks of an IBM 10MHz AT clone (AST) with 2 megabytes of RAM and
a 40-megabyte, 30-millisecond access hard disk--a powerful (costly) setup.
Using MS-DOS TYPE function Richard, scanning a 160k-byte text file from top to
bottom, produces these impressive measurements:
Condition Time, seconds
--------------------------------------------------
Standard DOS v3.1 150
DOS 3.1 with Fansi-Console 74
Same but with F-C hardware scroll 24
Fansi-Console has a fast mode by accessing the 6845 display controller chip.
F-C makes direct BIOS calls, bypassing the DOS output-to-console function.
Speed is equivalent to 67k-baud.
We used our Ampro 4MHz Z80 machine with 20-megabyte, 65-millisecond
access hard disk, Wyse 38.4k-baud terminal, testing three "type" programs at
hand, to scan 160k-byte text file. Echelon results:
Condition Time, seconds
--------------------------------------------------
VTYPE from ZRDOS v1.7 118
TYPE of ZCPR v3.3 97
"V" command of ZFILER v1.0f 68
VTYPE is slowest because of extensive character testing going on as text is
scrolled--scrolls forwards and backwards line-to-line or page-to-page, near
instant goto bottom-of-file or top-of-file from anywhere within file, in con-
text help, plus many other bells and whistles. TYPE is from command processor
(CCP) of ZCPR v3.3 and has option to stop automatically at screen page breaks.
�ZFILER's V command has line-by-line and page-by-page, and to end-of-file
scrolling abilities. Draw your conclusions as to how much faster a SemiDisk
9.2MHz DT42 would be over Ampro 4MHz Z80 (hint: see testing results in Z-News
409 and 501).
Thanks, Richard, for sharing your results with us. We recommend you
order today your longed-for DT42 computer.
Z-Node Activity. A programmer's tip that comes from Al Hawley, Z-Node #2
Sysop and present ZAS/ZLINK shepherd, suggests using ASET instead of EQU under
certain conditions. If you are having trouble with multiple same-label defi-
nitions coming from more-than-one, several "include" or "maclib" files, ASET
may be an answer. ZAS provides both these pseudo-op code possibilities. ASET
is useful when a label takes on more than one value during the course of
assembly. EQU permits a label to acquire but one value. ASET accepts getting
identical values from several sources during an assembly.
Software Update Service Report. Well, another SUS diskette is in the making.
Subscribers have received fair value: we promised you at least 9 diskettes per
year--we have already shipped 11. Here's how #12 looks at newsletter go-to-
press time:

Disk Directory v1.4 is alternative to DIR coming from Terry Hazen--a very nice
ZCPR3 utility. FOR-NXT2 are useful batch (FOR-NEXT-PERFORM) utilities, espec-
ially for RAM and fast hard disk users, from Dreas Nielsen, the Z-System shell
expert. Also from flinty Dreas comes Z3VARS, a library he uses to make easy
creation of shells and other utilities.
ZF10F is latest upgrade of ZFILER from Z-Team member, Jay Sage, author of
ZCPR v3.3. ZFILER v1.0f has macro-command file tagging facility, a real
break-thru for our shells. Jay soon further upgrade ZF to more than it is
now.
ZLDIR is NAOGer Bruce Morgen's update of Sigi Kluger's LDIR. ZLDIR is
fast, much faster than LLF but doesn't have some of LLF's bells and whistles.
We use ZLDIR in our TLF alias for seeing the text files to be scanned in a
library file (see below for an update to the TLF suite).
ZMANG-20 is Z-Node #60 Sysop Bob Peddicord's near-final product for file
management under Z-System. Menu shell is declared a "super utility" and will
find uses by those wanting extreme flexibility to manage application programs
and general housekeeping. Syntax is near identical to ZFILER making menu pro-
gramming easier. Soon all our shells will have similar parametric syntax and
grammar.
Z-User's Corner. Correctly placed hyphens within words permit lines to be
justified neatly flush left and right, with even and not too much space be-
tween words and characters. WordStar, Release 4.0, comes with The Word Plus,
TW for short, with expanded main dictionary of over 61,000 words. Earlier TW
had only 45,000 words. In addition to all the new WordStar features, math,
�macros, proportional spacing with right-margin alignment, TW adds word handl-
ing tools: SPELL, REVIEW, LOOKUP, FIND, ANAGRAM, MARKFIX, HYPHEN, WC,
DICTSORT, and WORDFREQ. You can run spell checks from WS's main menu and you
can run any command. As a ZCPR3 shell and utility, WS v4.0 knows paths and
named directories, command errors are turned over to installed error handler.
(We use Z33VERR from SUS #12.) From within WordStar, using the "R" command
from main menu, many aliases have been found useful, and actually at lot of
fun to design and develop.
hyph if ~nu $1;echo $0 - d%>etermine word hyphenation; <<
echo s%>yntax: $0<cr>;else;cls;echo e%>nter%< ctrl-c %>to exit; <<
echo;PRIVATE:;hyphen;$d0$u0:;fi
hf if //=$1;or nu $1;echo $0 - h%>yphenate words in a file; <<
echo s%>yntax: $0 <fn.ft><cr>;else;cls;A:;hyphen $d0:$1 $$4;$d0:;fi
HYPH followed by a <cr> causes TW's HYPHEN program to load and prompt the ope-
rator for a word. This word is the one you wish to know how to hyphenate.
Some built-in help is provided with alias script. If you enter other than
verb name, i.e., HYPH, followed by a return, you get the title and syntax mes-
sage. We use ECHO's lowercase switch, %>, after the first letter of messages,
Z-News 801-3. Leading spaces are used to line-up display text for a pleasing,
designed appearance. (Remember the "<<" convention. It means the line is
one, is continuous. Break is required because page is too narrow for multi-
ple-command line length.)
HYPHEN, written by Wayne Holder of Oasis Systems five years ago, is not a
Z-System utility. So, we have to use our wits (facilities of Z-System) to
make the command work from any directory. Here's what we do. Place
HYPHEN.COM and its "exception" file, HYEXCEPT.TXT, in a PUBLIC directory. Our
public directory is named PRIVATE, directory A6. After clearing screen with
resident CLS Z-System RCP command, needed to remove WordStar's prompt messag-
es, alias logs into PRIVATE, finds its TXT files and prompts with a "?".
Here, enter word for which you wish to determine hyphenation. A reminder is
displayed to use ^C to exit. On exit, you are automatically logged back into
your previous directory, the one from which you gave the alias command.
You may find HF, Hyphenate File, even more useful than HYPH. It places
soft hyphens into words of a selected file. Hyphens appear as "=" from within
WordStar v4.0 and Newword. These are called soft hyphens. Using ^OD causes
the hyphens to disappear, except the ones at the end of lines that print as
real hyphens. HF has built-in help we are accustomed to. Notice how the OR
is used to avoid repeating the help message. Alias is, as they say, "bullet-
proof." More tricks used here to make HYPHEN do what we want it to do. We
hard-log into directory A; HYPHEN is then given the drive letter (current
drive) on which to find the file, represented by $1, the one you typed in, in
which to place the hyphens. After we log back into our current directory from
where we placed the alias command. The "$d0:$1" phrase means current drive
and first parameter after verb on command line, in this case the filename of
the file to have hyphens placed into it. Trailing parameter "$$4" tells
HYPHEN to place hyphens in all words 4 or more characters long, the default is
10. Here's the built-in designed help displayed by the aliases after you
enter "<cmd> //<cr>":
HYPH - Determine word hyphenation HF - Hyphenate words in a file
Syntax: hyph<cr> Syntax: hf <fn.ft><cr>
� Aliases such as HYPH and HF are best put into an ARUNZ CMD script, saving
disk space over that occupied by normal one-file aliases. Above examples use
ARUNZ syntax and grammar, ready for ALIAS.CMD script file. See Z-News 701-3
for more on using ARUNZ as CMDRUN with LX and COMMAND.LBR, for speed and disk-
space conservation. Scan back issues of newsletter for many other alias ex-
amples. Now is the time to try your hand at creating more aliases to automate
further your operations. Let us see the results! To stimulate action...
We show one more alias (actually three): the reincarnation of TLF, Type
Library Files, originally developed by Rick Charnes from ideas of GH and GLF,
Get Help and Get Library File, Z-News 507-3 and 508-4, as set of recursive
aliases creatable only with VALIAS. Here we use Rick's technique inside
ALIAS.CMD as recursive script run by Jay Sage's ARUNZ.COM, renamed to
CMDRUN.COM. After, we show how we use TLF in a ZFILER script line to produce
a universal TYPE command for files squeezed, crunched, in libraries, and just
plain text.
tlf if //=$1;or nu $1;echo S%>yntax: $0 [du:]<libname><cr>;else; <<
ROOT:quiet s;/tlib2 $1;fi
tlib2 $z zif;ROOT:zldir $d1$u1:$:1;ROOT:getvar tlib file to type <<
(x=exit):;ROOT:resolve if x=%tlib;/exit;else;ROOT:resolve ROOT: <<
lt $d1$u1:$:1 %tlib;/$0 $1;fi
TLIB2 displays list of files, ZLDIR actually does it, within library,
prompts for file to be typed, the one you desire to scan. After you are
finished with selected file, list is shown again, prompt asks for another file
or for an "x" to exit.
Now for the ZFILER CMD line that pulls it together--makes magic--using
LT, TLF above, and VTYPE to scan various kinds of text files.
t!$d$u:;if lbr=$t;/tlf $n;else;if co $f;ROOT:lt $f;else; <<
ROOT:vtype $f;fi;fi;$h:
If file pointed-to is a library, TLF is run by ARUNZ renamed to CMDRUN,
our ECP. Note: "/" causes CCP to go directly to ECP for speed. If file is
squeezed or crunched, i.e., compressed, detection occurs using "co" operator
of Z33FCP; LT is called to type file. Finally, if file is plain text, VTYPE
does typing to screen.
ZFILER command script is run by pressing Escape key followed by "t" key
for type. You may wish instead to rename line "v" for view. Of course point-
er should be on file you wish to type, either file or library, squeezed or
crunched.
One final user thought: don't overlook usefulness of TCVIEW by Jay
Roumman, on SUS #8 and Z-Nodes, to show what your TCAP is.
Terminal Doings. We periodically report ASCII/ANSI terminal developments of
Wyse, IBM, DEC, and TeleVideo. What a competition! Now Hewlett-Packard jumps
into arena with its own models. Model HP700/22 priced at $575 is competitive
with WY-60 and TVI 955. IBM and DEC aren't in the running for value here.
Model HP700/41 takes ASCII low-end lead at $375 competing with WY-30 and TVI
905. HP quality at this price? Here again, IBM and DEC seem to have little
interest in new contest. Surely Wyse and TeleVideo counter recent HP moves?
� A word of caution to would-be giant killers: everyone
forgets what would have happened to David if his shot had
missed Goliath (I Samuel 17).
In Other Words. Words! Oh! Words! What words to use next! Words formed
from an alphabet make phrases into sentences, and in context, permit transfer
of thoughts from one human to another. That's language! "A systematic means
of communicating ideas or feelings by the use of conventional signs, sounds,
gestures, or marks having understood meanings."--one definition of the word
language from Webster's New Collegiate Dictionary, G&C Merriam Co., 1980
edition. Wow! A book could be written just to describe the words used to
define the word language: systematic, means, communicating, ideas, feelings,
conventional, marks, understood, meanings. Any wonder we fail to communicate.
Fail so often!
"When I use a word, it means just what I choose it to mean-
-neither more nor less. The question is, which is to be
master"--Lewis Carroll in Through the Looking Glass.
Usually when thinking of language our minds are brought to concepts of
spoken and written words (the marks of our definition), "verbalization" as we
often say. Now think of signs and gestures as elements of communication and
we know why we seem to do a better job when face-to-face as opposed to using
the telephone. These signs and gestures relay much of our inner being to any-
one in tune, and most of us are, to receiving such signals. Will machines
ever have such tune?
"A picture is worth a thousand words." We get into contextual mood by
re-reading Z-News 801, bottom of page 4 and all of 5. What and where are
thoughts? Thoughts become "concrete" when they are verbalized. Much of the
magic may be lost in the process. Why? The words don't fully convey the
vision they attempt to replace. Replacement tends to create an unreal vision
not of the original's quality.

Of Angels and Eagles. USA drifts into mold of managing wealth instead of cre-
ating it. Our brightest young people become lawyers engaged in litigation
with each other rather than making the country work. Our schools have far
more courses offered in marketing, engineering, and finance than in manufact-
uring--symptom of misdirected emphasis. Remember Z-News 606-3, "Manufactured
products lead to research and development which lead to engineering which
leads to manufacturing more products--a neat closed loop." Some of you
thought engineering and R&D should come before manufacturing. But manufactur-
ing usually creates the wealth of a nation. From there we get the money
("Where does money fit into our picture..." Z-News 305-5) to do R&D. Missing
this point is prime reason US has a $209 billion 1986 foreign debt.
Stanford University economist Nathan Rosenberg stated recently that near-
ly half the US patents were given out to foreigners--lawyers and arbitrageurs
don't create, they administer and manipulate that already created. Japan has
far fewer engaged in legal and financial work than we do. Most of them are
concerned about customers' needs and product design and quality. Our main
concern seems to be: when do we go home and start the weekend.
Nineteenth century England was birthplace of those causing the Industrial
Revolution: just about everything manual got electrically motorized. The sons
and daughters of these materially and spiritually rich people lost interest in
what their parents had wrought--so have most of us! Is USA simply to be one
of many players on the world economic stage, and not be lead-nation as we have
�been for so many years? See you down the lines...
