Two parameters are used by all exits, Work area and Action.
- Work area
- A 128-byte work area. The exit programs can use this area as a common
work area. The address of this work area is passed to all the exit programs,
enabling them to pass information among themselves. This area contains binary
zeros at the first exit invocation.
- Action
- A 1-byte character field containing a code that indicates what action CICS® VR
takes after receiving control back from the exit. Every exit program must
return an action code. Below is a list of possible exit codes accepted for
the CICS VR
exits:
- C
- Continue as if no exit program was provided.
- U
- Use the record that the exit program just updated.
- I
- Ignore the log record and read the next log record.
- S
- Terminate CICS VR
processing (CICS VR
batch backout ESDS delete exit only).
Refer to the individual description of each CICS VR exit
for a list of acceptable action codes for that exit.
