;EDITS MADE FROM VERSION 1 TILL 101

;1 FIX ETERNAL LOOP DUE TO TURNED AROUND MESSAGES GOING TO
;  A DISAPPEARED ORIGIN.THIS CAUSED [SYSTEM]INFO TO SEND TO SYSTEM 
;  INFO

;2 IILEGAL UUO'S WERE REPORTED WHEN A USER USED A PID OBTAINED
;  INDEPENDENTLY FROM 	SYSTEM]INFO

;3 IGNORE ERRORS CAUSED BY A LOGGED OUT JOB FOR WHICH A IPCF REQUEST
;  WAS MADE

;4 THROW  AWAY PAGES SENT BY ANNOYING USERS

;102	FIX INCORRECT DEFINITIONS OF EJECND AND NXMCND FOR ERROR TRAPPING
