Comment ^
The SETUP program was originally developed at the University of Montana
and is distributed by Carnegie-Mellon University, Pittsburgh,
Pennsylvania under the agreement that any modifications be communicated
back to C-MU and that no such modified versions be distributed to other
installations except by C-MU.
Revision History
[1] R. Swick 17-Oct-78. Raise lower case to upper case when expecting a
command, allow .MCF file to be given on EXEC command line and don't
replace "!" with ";" at beginning of line.
[2] R. Swick 18-Oct-78. Add line to beginning of .CTL file giving name
of .MCF file.
[3] R. Swick 18-Oct-78 Change ";Def spec cons" to ";Def variable",
make ";Def cons" a real constant (i.e., don't prompt user for value,
but get value from <text>).
[4] R. Swick 18-Oct-78 Don't raise terminal input by default.
[5] R. Swick 19-Oct-78 Change ;! to ;Type and ;? to ;Ask, and use TBLUK
jsys for parsing commands so whole word will be verified.
Version 2.
[6] R. Swick 26-Oct-78 Make ;Opt and ;No-opt check for ;Sel and
remove ;If ... commands.
[7] R. Swick 26-Oct-78 Add ;Include command.
[8] R. Swick 7-Nov-78 Fix bug in ;Select after ;Option or ;No-option,
Add ;Check-for, ;Abort, and ;Define option commands.
[9] R. Swick 9-Nov-78 Add /Verify switch to ;Define var and ;Select opt,
and don't verify by default.
[10] R. Swick 20-Nov-78 Use COMND wherever possible, remove prompting for
MCF file, and add /JOB-ID: switch to SETUP command line.
Version 3.
[11] R. Swick 21-Nov-78 Allow just @SETUP exec command to enter
recognition mode with SETUP> prompt.
[12] R. Swick 7-Dec-78 Fix bug in ;Ask, add /VERIFY option to ;Ask,
and fix bug in nested false ;Opt and ;No-opt's.
[13] R. Swick 8-Dec-78 Make SETSRC flag both upper-case and lower-case for
each character, so that case will be ignored for options and variables.
[14] R. Swick 2-Feb-79 Add re-parse address for COMND and help message
for /JOB-ID:.
[15] R. Swick 23-Mar-79 Add <job-name> pre-defined constant and insert
CRLF in record for ;Opt, ;No-opt and ;Check-for rather than deleting
beginning of line.
[16] R. Swick 16-Apr-79 Add ;File command.
[17] R. Swick 24-Apr-79 Add /TAG: switch to command line and abort if
job-id or tag is longer than 6 chars.
[18] R. Swick 2-May-79 Add /ALLOW and /SAVE switch to ;Define variable
and ;Select option commands.
Version 4.
[19] R. Swick 7-May-79 Major changes to how variables are found in
a line in REPVAR (formerly DO.FS).
[20] R. Swick 16-May-79 Remove vestiges of ;Check-for, add ;Get option
!variable and ;If "<string1>" [NOT] =!<!> "<string2>", ;Select
variable, ;Type <nul> to clear screen, clear screen on startup,
undefined options => no value.
[21] R. Swick 14-Jun-79 Add <current-year>,<current-month>,<current-day>,
<julian-date> pre-defined constants, give error for invalid and
ambiguous commands after ; and ;Error command.
[22] R. Swick 15-Jun-79 Add option for day of week.
[23] R. Swick 18-Jun-79 Add ;Perform command.
[24] R. Swick 23-Jul-79 ;Error will use @IF (ERROR) if only one command
was given in the text. ;Perform will undefine the variables used so
that multiple ;Performs may use the same variables. ;Abort on EOF
if any warning error occurred. Insert ; SETUP Version 4(24) input from
... after /TAG: label so that log shows this. Fix extra garbage from
;Include when EOF is reached. Make directory names work in filespecs
by breaking a word on ">" only when F%VNM is set. Be sure to check
for SETUP.BIN file larger than 1 page and provide /RESET switch for
resetting list interlocks.
[25] R. Swick 24-Jul-79 Add ;Perform ... <var1>,<var2>=filespec.
Allow wildcards in ;File ... found|not-found.
[26] R. Swick 24-Aug-79 Fix looping in ;Include when file not found.
[27] R. Swick 30-Aug-79 Don't try to write to .CTL file if found a fatal
error during initialization.
[30] R. Swick 11-Sep-79 Fix /DELETE switch to store correct block length
for the value of the thing deleted. Also, change STOEMP to store
blocks in increasing order by size.
[31] R. Swick 11-Sep-79 Add /BEGIN switch to ;Include to allow
specification of a BEGIN-OF-JOB-PROCEDURE.MCF, or something similar.
[32] R. Swick 25-Sep-79 When no files match a ;Perform ...=filspec, before
giving error msg, make sure that user did not specify a later /TAG:.
[33] R. Swick 2-Oct-79 Define an option Restart-<tagname> to be yes when
the /TAG: switch is used.
[34] R. Swick 3-Oct-79 Add line continuation syntax; "-",";+".
[35] R. Swick 4-Oct-79 Add compile-time parameter (BINMAX) for max # of
pages in SETUP.BIN and set it to 2 initially.
[36] R. Swick 9-Oct-79 Add /DEFINE and /NOECHO switches to ;GET and use a
common routine for parsing all command switches. Also trap all output errors
to CTL file (like Disk Full). Look for file type .SCF in ;Include
and ;Perform before looking for .MCF.
[37] R. Swick. 16-Oct-79. Don't require a space between ">" and hyphen to continue
a line and don't require spaces for a nul continuation line (";+-").
Version 5.
[40] R. Swick. 1-Nov-79. Fix /DELETE OPTION to not get illegal instr.
[41] R. Swick. 29-Nov-79. Fix generation of CTL file name to always add NUL
after the file type.
[42] R. Swick. 23-Jan-80. Add /DEFAULT:"<text>" switch to ;Define variable
and ;Select option commands.
[43] R. Swick. 23-Jan-80. Open SETUP.BIN for restricted access when /RESETing.
[44] R. Swick. 23-Jan-80. Add [NOT] NUMERIC condition to ;If.
[45] R. Swick. 30-Jan-80. Add <CURRENT-USER-NAME> system constant.
[46] R. Swick. 13-Feb-80. Add control-C trapping so SETUP.BIN doesn't
get blown away.
[47] R. Swick. 14-Feb-80. Add ;Leave command and use short GTJFN in
PFMGFL so as not to assume any unfortunate defaults (such as MCF:!).
[50] R. Swick. 15-Feb-80. Add ;Begin and ;End commands, make ;Leave work
for blocks also.
[51] R. Swick. 21-Feb-80. Fix PFMNXT to correctly round value length
in words so that 4-char values no longer confuse it.
[52] R. Swick. 25-Feb-80. Remember to check F%FLS in LEAVE so as not
to leave blocks prematurely.
[53] R. Swick. 1-Mar-80. Fix ;Performed blocks to not get errors when
block was really suppressed. Also fix ;Perform/verify. Add
<CURRENT-HOUR> pre-defined constant.
[54] R. Swick. 21-Mar-80. Add MCFLOG: and MCFTRACE: logical devices
with logging and tracing functions.
[55] R. Swick. 22-Mar-80. Add <Current-Month-Name> pre-defined
constant and align all values in log display.
[56] R. Swick. 28-Mar-80. Add tag + offset to trace output and fix
left-justification of lines prior to checking for continuation.
[57] R. Swick. 24-Sep-80. Add /SAVE switch to ;DEFINE CONSTANT and ;DEFINE
OPTION. Also show old value on SETUP/OPTION, SETUP/VARIABLE and SETUP/DELETE.
