Enterprise COBOL for z/OS, Version 4.1, Compiler and Runtime Migration Guide


Adding Enterprise COBOL programs that use static CALL statements

Under both CICS and non-CICS, you can create an Enterprise COBOL program that uses static CALL statements to call a VS COBOL II program. However, when you link-edit the load module with Language Environment, you must have the appropriate level of IGZEBST, the VS COBOL II bootstrap:

If you do not have the correct level of the IGZEBST routine, you will encounter a program check when the VS COBOL II program is called.

Although VS COBOL II applications link-edited with IGZEBST from VS COBOL II that does have PN74000 installed will run with Language Environment, they will not cause the Language Environment user exit (CEEBXITA) to get control. This results in reduced functionality. For example, easy startup of Debug Tool is not available. IBM recommends that you relink all of your applications that have IGZEBST, and REPLACE the old copies of IGZEBST with new ones from Language Environment for z/OS.

For an example of link-edit JCL or sample jobs in Language Environment library SCEESAMP, members IGZWRLKA, IGZWRLKB, and IGZWRLKC see Link-edit example.
