JES2 exit processing for JOBGROUP JCL

Certain JES2 exits are called during input processing for a job group. Exits 2/52 are called for the JOBGROUP card, exits 3/53 are called for the accounting information on the JOBGROUP card, exits 4/54 are called for each JCL card after the JOBGROUP card (up to the ENDGROUP card), Exits 20/50 for the end of input, and exit 7/8 for CBIO. Data areas passed to these exits are the same as any other batch job. However, The JCL statements are the new statements detailed later in this section.

After input processing, the normal job phase exits are called for the job (for example, exit 51 for phase changes). JOBGROUP logging jobs move from the INPUT phase to the SETUP phase, then the OUTPUT and HARDCOPY phases, and finally to the purge phase.
