124	 -----	ADDED MAIN ENTRY SYMBOL MRP0 FOR SINGLE SEGMENT COMPILER
		/HPW
125	 -----	ADDED BUGOUT COMPLIER DIAGNOSTIC SWITCH /DBT
126	 -----	FIXED ERROR TRAP TO CLEAR FIRST PART DONE
127	 -----	CHANGED SIZE OF POOL
130	 -----	MOVE APR TRAP INITIALIZATION TO BE RESET AFTER
		EACH PROGRAM
131	-----	CHANGED BIT POSITION OF EOCS BIT IN FLAG REGISTER
132	-----	PUT BOUNDS SWITCH BACK IN
133	-----	CHANGE NXTFIL TO A SUBROUTINE WHICH WILL OPEN THE INPUT
		FILE AS WELL AS BUILD THE OPEN BLOCK. PHAZ1 CAN THEN CALL PHAZCO
		AND THEN NXTFIL SO THAT THE "+" COMPIL CONSTRUCTION
		WILL WORK
134	-----	FIX ABSENT SPEC (PRESENT SWITCH)
		BEING TREATED AS PRESENT SPEC. E.G. /SWT,X=X
