OS/VS COBOL
If the user exit routine is written in OS/VS COBOL, you must compile it with the NORESIDENT and NODYNAM keywords. If the OS/VS COBOL program uses the DISPLAY statement, compile it with the ENDJOB keyword. If you use NOENDJOB, each execution of the DISPLAY statement uses additional virtual storage. Eventually, an S80A abend could occur. If the user exit reads or writes an external file, NOENDJOB is required. To prevent a storage problem, limit the number of DISPLAY statements.
