Modifying the OS/VS COBOL compatibility library routines

Use the IGZWZAP sample job to modify the OS/VS COBOL compatibility library routines. The job lets you apply superzaps to make Language Environment COBOL behave like OS/VS COBOL. See Table 1 for a summary of the modifications you can make with the job. OS/VS COBOL considerations explains the superzaps in detail.

Table 1. Using the usermods in the IGZWZAP job to modify the COBOL compatibility library
Usermod	Contains superzaps to	For
IGZWZA1	Continue to force USER ABEND 0100, 0201, 0303, or 0304 and message IFK302I	Certain error situations during VSAM file processing
IGZWZA2	Force USER ABEND 0295	A serious error detected at runtime
IGZWZA3	Add A, B, and E as valid numeric signs	The IF NUMERIC CLASS TEST

To modify the JCL for IGZWZAP:

Change #GLOBALCSI to the data set name of your global CSI data set.
Change #TZONE to the name of your target zone.

IGZWZAP should run with a condition code of 0.
