This central program is used for diverse functions dealing with PO data sets. The processing of the various functions takes place via ISPF services. Compared to their TSO equivalents they are better and quicker in many areas. For instance, a member can only be erased with the TSO DELETE command when TSO manages to assign the whole data set exclusively at the time of deletion (DELETE allocates the data set with option OLD, even if only one member of it is supposed to be deleted). Often this is simply not possible for heavily frequented data sets.

How to use
DATEI = "SPGMBH.TEST.DATA"
mbr_list = PDS$E(DATEI,"MBRLST")        /* chain of words with membernames */
mbr_list = PDS$E(DATEI,"MBRLST","AB*")  /* chain of words with membernames starting with AB */
