If the COBOL programmers at your site are familiar with OS/VS COBOL, you may want to modify Language Environment COBOL to make it behave like the OS/VS COBOL runtime. The IGZWZAP member is a sample job provided in CEE.SCEESAMP to apply USERMODs IGZWZA1, IGZWZA2, and IGZWZA3, which are described in the following sections. For instructions on modifying the JCL for the IGZWZAP job, see Modifying the OS/VS COBOL compatibility library routines.

User modifications for the OS/VS COBOL library also apply for the OS/VS COBOL compatibility library routines.
