User Exits
CA XCOM Data Transport user exits allow users to modify characteristics and capabilities of CA XCOM Data Transport software by inserting their own routines at various positions, known as exit points, in the source code. This appendix provides information about all currently available user exits. The information provided about each user exit includes:
- Purpose
- Module name and entry point
- Method of enabling the user exit
- Name of the CA XCOM Data Transport module from which the user‑supplied module is called
- Method of entry (implying the relationship between the two modules)
- Name of the required DSECT
- Addressing mode at entry
- Information about entry registers
- Information about exit registers
- Return codes
- Location of a sample program
Important! If you are upgrading to a new release you need to reassemble and link‑edit your user exit programs.
