	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.
