Programming considerations

The following are programming considerations for Exit 46:

If your installation needs to process NJE data areas differently for spool offload processing and NJE processing, use field DCTDEVTP in the $DCT to determine the type of job JES2 is processing.
Locating the JCT Control Block Extensions
You can locate extensions to the job control table ($JCT) control block from this exit using the $JCTXGET macro. For example, you can use these extensions to retrieve job-related information from the $JCTX control block to ship across the network in $NHD macro sections. For more information, see z/OS JES2 Macros.
