After invoking ISMF and choosing the data set application from the ISMF Primary Option menu, you need to build a data set list to use during the session. To do this:

1. Complete the Data Set Selection Entry panel with the values shown in Figure 1 to generate the list from the catalog and acquire data from the VTOC for data sets that have been migrated by DFSMShsm. Verify that pages 2, 3, and 4 of the Data Set Selection Entry panel are blank. If they are not blank, you will receive the short informational message: OTHER VALUES PRESENT.
