Function

Use exit 41 to affect which OUTPUT JCL keywords JES2 uses for generic grouping.

JES2 passes this exit a table that contains the SJF keys for the default generic grouping keywords. There is a one-to-one correspondence between the SJF keys and the OUTPUT JCL keywords. You can use this exit to add keys to or delete keys from this table. You can add up to 24 additional keys at the end of the table. Delete keys by compressing the table.

Generic grouping cannot perform special processing for keywords (such as handling defaults or overrides). A keyword should not be grouped generically if it has any of the following attributes:

The keyword can be overridden by another source. CLASS, DEST, and WRITER can be overridden on the DD statement. The network SYSOUT receiver uses the group id in a data set header; the group id might have been generated by the execution node and thus not be present on the OUTPUT statement.
The keyword can be specified at dynamic unallocation (for example, CLASS).
The keyword has a default value that JES2 must provide. DEST, OUTDISP, and PRMODE, for example, have default values.
The keyword can be specified in an alternate way (for example, HOLD=YES on the DD statement is equivalent to OUTDISP=HOLD).

Keywords that require special processing should be managed by the PDDB and be grouped upon by the output processor.

JES2 passes this exit the name of the JCL definition vector table (JDVT) that defines these keys. The table of OUTPUT grouping keys applies to all OUTPUT statements processed using this JDVT.
