Control-D decollation considerations
Control-D decollation can decollate one or more SYSOUTS of the same job. The selection of the required SYSOUTS can be done by using the SYSOUT DDNAME. Sometimes, the order of the decollated SYSOUTS is important for the SYSOUT distribution.
If the job that produces the SYSOUT is split by Job Optimizer, the Job Policy Spool scheduling option determines how the step’s SYSOUTs are gathered back to the job. Specifying the value of DEFER in the Spool scheduling option tells Job Optimizer to gather the SYSOUTS in the same manner as for normal sequential processing and to retain their ddnames.
Control-D uses the step number as part of the data set name when allocating files. Use the STEPNUM ON setting to force Job Optimizer to set a split step to its original step number.
