If you are building a module that will be fetched and which has an Enterprise PL/I routine as its entry point, then the ENTRY card should specify the name of that PL/I entry point. If the module is to be fetched from Enterprise PL/I, you may specify CEESTART on the ENTRY card, although this is strongly not recommended. However, if the module is to be fetched from COBOL or assembler, then the ENTRY card absolutely must specify the name of the PL/I entry point into the module and not CEESTART.
