You can find complete information about JCL in the following publications:
Beginning in z/OS V2R1:
- Use the DDNAME parameter on the OUTPUT JCL statement to specify the DD statements to apply the specifications on the OUTPUT statement to.
- Use the DSNTYPE parameter on the DD statement to specify a new partitioned data set extended (PDSE), or library, and an optional version level for the new PDSE.
- Use the GDGORDER parameter on the DD statement to specify an order in which the generation data sets are processed.
Use the MAXGENS parameter
on the DD statement to specify the maximum number of generations for
members in a version 2 PDSE. This requires APAR OA42358.
- Use the MERGE parameter on the OUTPUT JCL statement to specify whether to merge OUTPUT JCL statement parameters with the job output statement.
- Use the REFDD parameter on the DD statement to specify a DSNTYPE for a new data set.
- Use the RLSE subparameter on the SPACE parameter, with a multi-volume sequential data set, to release both unused space on the current volume and allocated space for the data set on subsequent volumes.
- Use the SYMBOLS parameter on the DD statement to request for JES to perform symbol substitution within in-stream data.
- Use the SYMLIST parameter on the DD statement to list the symbols to pass to the internal reader (INTRDR).
- Use the SYMLIST parameter on the EXPORT statement to make specific JCL symbols available to the job step program.
- Use the SYSAFF parameter on the JOB statement to indicate the JES2 members and JES3 systems that are eligible to process the job.
- Use the SYSTEM parameter on the JOB statement to indicate the systems that are eligible to process the job.
Beginning in z/OS V1R13, you can use the FREEVOL parameter to allow different systems in the sysplex to read multivolume tape files more efficiently. The FREEVOL parameter lets you specify whether to allow other jobs to read freed volumes of a multivolume tape file as the volume is dismounted by the job.
