This (E)JES JES compatibility matrix provides a historical look at which JES2/JES3 releases are supported by the latest (E)JES releases. This matrix is for informational purposes; mention of any back-level z/OS release in this matrix does not imply that the release is currently supported or maintained by IBM.
|OS Release||(E)JES V5R5||(E)JES V5R4||(E)JES V5R3||(E)JES V5R2|
