Decollating from Compressed Datasets

Decollation from compressed datasets that have been created directly from a job (using parameter SUBSYS) has the following characteristics:

• Decollation is only carried out on the compressed datasets specified in the job decollation criteria (that is, not necessarily all outputs of the job).
• It is possible to select reports for decollation by step name and DD name of the job.
• Control-V maintains all the printing characteristics (including laser) that were specified in the DD statement that created the SYSOUT. Therefore, there is no need to specify any data in the PRINT/CDAM PARMS field.

Sometimes it is necessary to test the decollation criteria of a large report that cannot be easily produced for testing. There is a simple technique that allows both decollation by Control-V and normal printing by operators, without having to rerun the job that produces the report.

The JCL OUTPUT statement allows you to route a SYSOUT to more than one destination by defining one copy for LOCAL printing and another for DEST Uxxxx or one copy to the regular output printing class and the other to a held output class. (Refer to your JCL manual for further details.) The report is deleted from the spool after Control-V has decollated it, and the printer has printed it. For example:
