CBLPSHPOP(ON) ensures you receive behavior that is compatible with the behavior of running VS COBOL II programs with the VS COBOL II run time. CBLPSHPOP(OFF) can give performance benefits. For details, see CICS HANDLE commands and the CBLPSHPOP runtime option.
To receive the Language Environment-equivalent of the VS COBOL II WSCLEAR runtime option, set the first suboption of the Language Environment STORAGE runtime option to 00. For example, STORAGE(00,NONE,NONE,0K).
The IBM-supplied default setting is STORAGE(NONE,NONE,NONE,0K).
