Defining ISPF Temporary Data Sets for Batch Build

Use Option 12 in the Customization Dialog Settings Menu panel to define the data sets for the batch build.

SA z/OS displays the ISPF Temporary Data Sets Preallocation for Batch panel (see Figure 1).

This panel allows you to add or modify job control data to preallocate temporary ISPF data sets that are used for the batch build. The build function creates the ACF and AMC output files in two steps:

  1. All members are created and stored in a temporary file using ISPF file tailoring.
  2. This file is written to disk creating all the individual members.

To hold the intermediate files, ISPF work and control data sets are used. If the default allocations of ISPF are not sufficient, they can be changed on this panel.

The ISPWRKx ddnames are used by ISPF for file tailoring services. The ISPCTLx ddnames are used by ISPF to hold the file tailoring output and to pass it to the subsequent functions that write the members to the output data set.
