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
