;V12A****************
;WTK	 8-Jan-81	[1111] PERFORM LIMIT EXCEEDED when doing many executions of DECLARATIVES.
;DMN	 1-FEB-80	[762] IMPLEMENT AND USE D. P. FLOATING POINT LITERALS

;V12*****************
;DAW	28-SEP-78	[561] FIX "GO DEPENDING" - /O PROBLEM

;V10*****************
;	10-AUG-76	[435] PUT IN CODE TO JUMP AROUND DECLARITIVES IN A DBMS PROG
;	14-APR-76	[425] FIX KPROG CALL IN NON-RESIDENT SECTION.
;DBT	1/20/75		SET AND CLEAR FLAG INDICATING INSTRUCTIONS
;			NOT BEING PUT INTO ASY RATHER LITTAB
;			SET AT SEGCLN AND CLEAR AT EBURPX
;DBT	1/18/75		IN GOENTR AND GOALTD THE REVERSED ORDER

;			UUO CONVERTER - REVERSE THEM
;			ALSO EXITRP
;			IT IS NOT CLEAR THATTHIS WILL WORK BUT IT'S
;			WORTH A TRY
;ACK	22-APR-75	CONVERT LITAB EBCIDC CODE TO ASYFIL EBCDIC
;			CODE WHEN TRANSFERING LITERALS TO THE ASY FILES.
;********************

; EDIT 271 FIX SO THAT GENERATED PARA NAME NEVER GETS TRACED
;**; EDIT 210 ADD TO FIX 167-LITTAB OVERFLOW
;*;	EDIT 167 JEC 3/14/74 FIXES LITTAB OVERFLOW.
;		IN THIS ROUTINE THE REQUIREMENT THAT THE ENTIRE
