For executable files that have the set-user-ID or set-group-ID bit set, there are restrictions on the data sets that can be built into the STEPLIB environment for the file to run in. The systems programmer maintains a STEPLIB sanction list of data sets that can be included in the STEPLIB environment for such executable files. Only data sets on that list are built into the STEPLIB environment for such files. If you need a data set added to the list, contact your systems programmer.
