The following is taken from the Alpha Micro ISSG Newsletter:
In response to a letter from one of our readers asking for a list of
temporary filesnames according to the program in which they are used,
we have researched the subject and compiled the following information.
When determining file names to be used on the Alpha Micro computer, the
user should be aware that certain extensions are utilized by the
operating system and some programs for particular tasks. For example,
it might seem desirable to name a temporary file TEMP.TMP; however, if
this file were to be VUE'd, it would be erased because the VUE program
always changes the extension of any file being VUE'd to .TMP. After
exiting VUE, files with the extension .TMP are deleted. To assist in
determining which extensions are "safe" for general use, the following
list of file extensions should be used carefully.
TMP, BAK - Deleted or replaced by EDIT and VUE if a file of the same
name is edited.
PRG, IPF, OBJ, SYM, MAP - DELETED or REPLACED by MACRO, LINK and SYMBOL
if files of the same name are assembled, linked or SYMBOL'd.
PCF, PCT, PO1, PO2, PO3 - Deleted by PASCAL if file of the same name is
compiled or PLINK'd.
RUN - Deleted by BASIC or COMPIL if program of the same name is compiled
or saved.
LST - Deleted by MACRO, SRCCOM, TXTFMT or PDLFMT if a file of the same
name is processed.
TOC - Deleted by TXTFMT if a file with the same name generates a table
of contents.
IDY, IDX, IDA - Deleted by ISMBLD if a file of the same name is created.
All three are used by ISMBLD, ISMDMP and ISAM in BASIC.
GLB - Deleted by GLOBAL if a file of the same name is processed.
DVR - Deleted by FIXDVR if a file of the same name is created.
SRT - Deleted by SORT, AMSORT and BASORT if a file with the same name as
the jobname is used.
In addition to the above, it should be pointed out that several
extensions are recognized by the operating system and some programs, and
are handled based upon that extension. For example, if a file with the
extension .BAS is processed with a GO command from VUE, the VUE program
will default to running the COMPIL program on that file.
BAS - BASIC source file, COMPIL will be executed from VUE.
MAC - MACRO source file, MACRO will be executed from VUE.
LSP - LISP source file, LISP will be executed from VUE.
PAS - PASCAL source file, PDU.DO will be executed from VUE.
LIB - PASCAL library file.
TXT - TXTFMT source file, TXTFMT will be executed from VUE.
PDL - PDLFMT source file, PDLFMT will be executed from VUE.
CMD - AMOS command file and can be executed from VUE.
DO - AMOS DO file.
JNK - Recognized by log program if in [7,2].
HLP - Help file extension recognized by HELP.PRG.
VUE - VUE initialization and menu files (INI.VUE, MENU.VUE).
FIX - FIX initialization files (INI.FIX).
INI - System initialization files (SYSTEM.INI, PRINTR.INI), MONTST will
be executed from VUE.
