;The CMPRES routine tidies up command strings for the COMPILE-class
;commands.  Lots of these petty chores are normally handled by the monitor
;via the COMND jsys.  However, since the PARSE routine doesn't use COMND,
;this CMPRES routine is needed.
;CMPRES does the following:
;
;	o	Carriage returns are ignored.  Linefeeds are changed to
;		commas.  This is so that multiple-line indirect files work.
;
;	o	All multiple spaces are compressed to at most one space
;
;	o	Any spaces following end of line are
;		deleted.  Neglecting to remove spaces at end of line causes
;		"COMP FOO.MAC " to force a compilation.
;
;	o	Spaces preceding percent signs are deleted.
;		If spaces aren't removed in front of percent, the command
;		LOAD FOO %"text" fails to call the compiler!
;	o	Comments enclosed in exclams (!) are removed
;
;	o	Comments starting with semicolon (;) last through the next
;		linefeed or end of command
;
;	o	All spaces other than those sandwiched between filespecs
;		are removed.

;OR SOMETHING LIKE THAT.  HOWEVER, THE ORIGINAL GTJFN WE DID WITH
;NO BITS ON WILL FAIL ON "COMP X:FOO" WHERE X: IS DEFINED WITH
;"DEFINE X: (AS) <A>,<B>", AND DIRECTORY <A> IS NOT WRITABLE BY THE

;WHEN LOOKING FOR "FOO" IF NOT FOUND IN <A>.
;ACTUALLY, OLD-FILE-ONLY WILL ALSO FAIL FOR "COMP X:FOO"!  HOWEVER,
;IF FOO.MAC IS UNIQUE IN X:, "COMP X:FOO$" WILL RECOGNIZE IT WITH
;OLD-FILE-ONLY.  BUT IF NO RECOGNITION IS ATTEMPTED, "COMP X:FOO" WILL
;FAIL, SINCE THERE'S NO OLD FILE CALLED "FOO" IN X:.  HENCE, IF OLD-FILE-ONLY
;FAILS, WE HAVE TO TRY PARSE-ONLY GTJFN!!  NOTE THAT PARSE-ONLY
