Edit #	Description
*********************************************************************
626	Prevent Z-errors from being fatal
627	Prevent spurious X-errors on JMPs between CSECTs and to globals.
630	Provide complete Z-error checking.
631	Correct action of .MEXIT within repeat blocks.(IRP,IRPC,REPT).
632	Preclude garbage generation if .IDENT has too many chars.
633	Make .MCALL work right all the time.
634	Make MACY11 accept .PDP10 pseudo-ops.
635	Clean up page 1.
*****************release*******************
636	Load .JBREN,fix a spelling error, add debug patch area.
637	Add .PSECT capability.
640	Add Cutler mods.
641	Add disable of default globals, dflt registers
642	Implement /RSX, different default source extension order,
	improved spacing in symbol table output.
643	Correct minor glitches in CCL -file handling.
644	Fix another .IRP problem;i.e., correct action of macro defs
	inside .IRPs.
645	Force .IF IDN and .ASCII to accept null strings.
646	Not used.
647	Correct a .PSECT bug.
650	Correct action of default globalization.
651	Take one giant step backward. Skip 650, modify 647 and
	really correct default globalization.
652	Add SWITCH.INI capability and expand local symbol range.
653	Simplify default global disabilization.
654	Make SWITCH.INI processing take line numbers and
	upper/lower case.
655	Eliminate form feed before reprint of command line at
	end of listing.
******************RELEASE******************
656	ADD "JOB" LOGGING VIA SUBROUTINES IN LOGREC AND
	LOGAPP.
		****** NOW MUST BE LOADED WITH COMMAND STRING *****
			.LOAD MACY11.NNN,LOGREC,LOGAPP
		***************************************************
	LOGGING IS DONE IN DSKZ:JOB###.LOG[350,3004]
******************RELEASE******************
657	FIX "?LOGENT ENTER FAILURE"
	    "[NOT LOGGED]" JUNK FROM JOBLOG
******************RELEASE******************
660	REMOVE (BY COMMENTING OUT) THE "JOB LOGGING" CAPABILITY INSERTED
	IN EDITS 656 AND 657 IN ORDER TO DISTRIBUTE MACY11/LNKX11 THROUGH
	DECUS WITHOUT THE 'LOGREC' AND 'LOGAPP' SUBROUTINES.  HDT, WESLEYAN
	UNIVERSITY, APRIL, 1979.
	PROGRAM IS NOW LOADED AS .LOAD MACY11
