You should review jobs that call IEHPROGM because this utility is highly device-oriented. The following changes apply to IEHPROGM processing for system-managed data sets:

• CATLG and UNCATLG options are not valid.
• SCRATCH, RENAME VOL parameter device type and volume lists must accurately reflect the actual device where the data set was allocated. You and SMS-not the user-control device selection.
• SCRATCH causes the data set to be deleted and uncataloged.
• RENAME causes the data set to be renamed and recataloged.
• SCRATCH VTOC SYS supports both VSAM and non-VSAM temporary data sets.
