Deleting a USERVAR z/OS Communications Server: SNA Customization SC27-3666-00 |
|
When VTAM® invokes the USERVAR exit because a USERVAR is being deleted, the exit removes the UVCB for that USERVAR and frees the storage. If the exit cannot find the correct UVCB, the exit sets the return code to 0 and returns control. Likewise, if any of the processing required to delete the USERVAR fails, the return code is set to 0 and the exit returns control. |
