When allocating a new SMPTLIB data set during RECEIVE processing, SMP/E checks the format of the associated relative file (RELFILE) data set, then uses the appropriate data set type (LIBRARY or PDS) for the SMPTLIB data set. Here are some benefits of this change:

• When packaging SYSMODs, you can ship program objects in RELFILEs, because SMP/E can load RELFILEs that were created from PDSEs into SMPTLIB data sets that are PDSEs.
• When receiving SYSMODs, you do not have to preallocate SMPTLIB data sets with the appropriate data set type, because SMP/E can allocate the SMPTLIB data set as PDS or LIBRARY, based on the format of the corresponding RELFILE data set.
