* Exit Point Name : QIBM_QZDA_ROI1
*
* Description : The following ILE C/400 program logs all
* requests for catalog functions to the
* ZDALOG file in QGPL.
* It can be used as a shell for developing
* exit programs tailored for your
* operating environment.
*
* Input : A 1-byte return code value
* X'F0' server rejects the request
* anything else server allows the request
* Structure containing information about the
* request. The format used by this program
* is ZDAR0100.
*
* Dependencies : The log file must be created using the
* following command:
* CRTPF FILE(QGPL/ZDALOG) RCDLEN(132)
