Operation
CMS/OS:
IF A SPIE EXIT ROUTINE HAS BEEN SPECIFIED, AND IT IS NOT
ALREADY ACTIVE, THEN CONTROL PASSES THERE, AFTER A 'PIE' HAS
BEEN ALLOCATED IN USER STORAGE. WHEN CONTROL RETURNS FROM
THE EXIT ROUTINE, THE MODIFIED PGM OLD PSW IS LOADED, AFTER
ANY MODIFIED REGISTERS HAVE BEEN RE-LOADED.
IF A SPIE EXIT ROUTINE CANNOT BE TAKEN, THEN AN ERROR MESSAGE
IS TYPED OUT, AND CONTROL IS PASSED TO DMSABN, THE ABEND
RECOVERY ROUTINE.
CMS/DOS:
IF LINKAGE HAS BEEN ESTABLISHED TO A PROGRAM CHECK
ROUTINE (STXIT PC), CONTROL IS PASSED TO THIS ROUTINE.
IF NO LINKAGE HAS BEEN ESTABLISHED TO A PROGRAM CHECK
ROUTINE, A CHECK IS MADE TO SEE IF LINKAGE HAS BEEN
ESTABLISHED TO AN ABNORMAL TERMINATION ROUTINE (STXIT AB).
IF SO, CONTROL IS PASSED TO DMSBAB WHICH WILL GIVE CONTROL
TO THE STXIT AB ROUTINE.
IF NO PC OR AB ROUTINE CAN BE GIVEN CONTROL, CONTROL
PASSES TO DMSABN.
