Our issue is there seems to be a disconnect, or no link, between our SELECT statement and our SD. We had SELECT SORT-FILE and SELECT SORT-FILE ASSIGN TO SORTWRK. ASSIGN TO SORTWRK1 SORTWRK2 SORTWRK3 SORTWRK4. with SD SORT_FILE RECORD CONTAINS 7833 CHARACTERS. In either case, at run time, the system ignored our SORTWRK# DD statements and allocated 16 sort works with the SORTWK## naming convention. Any ideas why the system does not recognize the connection? We do not even need the SORTWRK DD statements. Thanks

Thank you in advance.
