User Written Exits in IDMS

The IDMS Data Adapter has the ability to execute user written programs via the ZBIND and ZREADY exit facilities.

Topics:

IDMS ZBIND Exit (MVS Only)

IDMS ZREADY Exit (MVS Only)

IDMS ZBIND Exit (CMS Only)

IDMS ZREADY Exit (CMS Only)

These programs can be written in any IDMS supported language and must be link edited to the IDMS load module IDMSR.

For release 12 and above, ZBIND and ZREADY exits must be link edited as AMODE(31), RMODE(ANY). The user written programs initiated by the ZBIND and ZREADY exits must be link edited as AMODE(24), RMODE(24) for release 10.2 of IDMS.

The ZBIND and ZREADY exits can call any user-specified program. The IDMS Data Adapter passes back to FOCUS a 4-byte status code. A non-zero status code indicates an error condition.
