To change the current record within the SMPPTFIN data set, the exit routine must change the record currently in UX001RCD and set the return code in register 15 to 0 or 20. A return code of 0 indicates to SMP/E that the changed record should be processed and normal processing should continue. A return code of 20 indicates to SMP/E that the exit routine inserts records after this changed record. For more information, see Inserting records within SMPPTFIN.
