Change JES3 release level format
Description
In z/OS V2R1 SSI 54, SSI 82,
and SSI 83 report the JES3 release level using the JES2 format z/OS
2.1. In previous versions of z/OS, JES3 reported the release
level using the format z 1.13.0. The SSI fields which
are affected by the format change are:
- SSI 54: SSVIVERS field from macro IEFSSVI
- SSI 82: JPXVERSN field from macro IAZJPLEX
- SSI 83: JPSYVERN field from macro IAZJPLXI.

Target system hardware requirements: | None. |
Target system software requirements: | None. |
Other system (coexistence or fallback) requirements: | None. |
Restrictions: | None. |

Steps to take
Follow these steps:
- Search for fields SSVIVERS, JPXVERSN and JPSYVERN in invocations of SSI 54, SSI 82 and SSI 83.
- For any code that requires the z/OS 2.1 JES3 release level, change the expected format to 'z/OS 2.1' (z/OS #.#).
