The control card override enhancement lets you specify a set of override libraries for control card members of system utilities. The override libraries are searched before the library specified in the JCL is validated. You can use this enhancement in invocations of CA JCLCheck from batch, ISPF, and EDCHEK.
Note: System utilities refer to utilities that CA JCLCheck validates and syntax checks using the CTLSCAN option, and that are present in JCLUPT.
Typically, control card override is used when CA JCLCheck is called from CA Endevor (batch or foreground). A control card member can reside in any one of a list of promotion libraries, for example, QA, development, and production. When you use this option, CA JCLCheck searches all promotion levels for the particular control card member. If the member is found in one of these libraries, that member is used for JCL validation. If not found in any of the promotion libraries, the control card member referenced in the actual SYSIN DD (or whichever DD statement the $UPT CTL keyword points to) is used for JCL validation.
