You can dynamically change JCLNeat options from a running REXX program with the JCLNeat feature Dynamic Option Changes. REXX programs can also reset JCLNeat options back to their initial run-time settings. When JCLNeat options are changed or reset, the change takes effect immediately on the formatting of the current statement being processed. The changes remain in effect until changed again, reset, or job termination.
You can specify any combination of supported options simultaneously up to a length of 120 bytes. Options are parsed and processed as they are when specified at the start of a job; however, not all options are supported dynamically. Invalid options that are specified dynamically are flagged and ignored, but JCLNeat processing continues.
The following options are not supported: FORMAT, INLIB, JOBF, LINES, MEMBERS, MKW, MQKW, OPTDESC, OUTLIB, RECOVER, REPORT, REXXMEM, and SIM.
Note: For more details, see the sample REXX program CAZ1NREX.
