Customizing the Exit

Modify the exit to invoke the required decrypt algorithm, set the return, and reason codes accordingly. The decrypted data returned cannot exceed the value pointed to by DCMAXDTL. Ensure DCRC points to the relevant return code. Return control to the caller using the value passed in Register 14 at entry. All registers except Register 15 must be restored. Results are unpredictable if invalid data is returned.

Note: Be sure to use the source that corresponds to your IMS release.
