CICS VSAM Transparency for z/OS, Version 1.2


Assembler exit coding rules

Exits are assembler and must be written as reentrant and reusable. A 16k work area is provided for and FBE and for IRD exits. Use the exit work area for your program save area. The work area is not changed by CICS® VT and the same area is shared by FBE and IRD exits. This allows you to pass it between FBE and IRD exits.

Exits that contain SQL calls should use an EXEC SQL INCLUDE member containing a DSECT defining the SQL host variables. Alternatively, you can use a DSECT that is based on the 16K exit work area EXWRKA (and IRDWRKA).

For IRDs that include SQL, include the module VIDHLI in your linkage edit. This is to enable the exit to be shared between CICS and batch programs.
