So if you have: ... //SORTIN01 DD ... //SORTIN02 DD ... //SYSIN DD * OPTION EQUALS MERGE FIELDS=(...) SUM FIELDS=NONE or ... //SORTIN02 DD ... //SORTIN01 DD ... //SYSIN DD * OPTION EQUALS MERGE FIELDS=(...) SUM FIELDS=NONE the SORTIN01 record will be kept for duplicates. If NOEQUALS is in effect, it's random.
