Note: You can only perform this function in an ISPF environment.
When specifying option J (JCL) in the Job List screen or the Active Environment screen to edit the JCL member, Control-M must determine which library (MEMLIB or OVERLIB) to use.
The algorithm for this decision depends on:
Table 206 indicates which libraries are used, depending on the above criteria.
Table 206 OVERLIB Parameter: Algorithm for LIbraries Used when Option J (JCL) is Specified
When the following CTMIMAC is defined (if any)... |
...the member exists in either library MEMLIB, OVERLIB, both, or neither |
...and the screen of the J (JCL) request is: |
... and the edit is performed in the following library |
---|---|---|---|
None (default) |
MEMLIB only |
Either screen |
MEMLIB |
OVERLIB only |
Either screen |

Note the following points:
For concatenated libraries, if the ©MEM parameter in Exit CTMX014G is set to YES, the saved member is placed in the first library of concatenation. If the ©MEM parameter is set to NO, the saved member is placed back in the original JCL library.
