When you use the VS COBOL II run time on CICS, attempts to use the DISPLAY statement in a VS COBOL II program causes a transaction abend.
When you use DISPLAY UPON SYSOUT (or just DISPLAY without specifying any UPON value) from a VS COBOL II, IBM COBOL, or an Enterprise COBOL program with Language Environment, the display output is written to the transient data queue CESE.
