Use FIELDS=COPY to copy one or more input files. Multiple files can be copied if they are concatenated to the SORTIN DD statement. Other control statements such as INREC, INCLUDE/OMIT, OUTREC, and OUTFIL may be specified in conjunction with a copy application, allowing you to edit and reformat the file(s) without sorting them.
The SUM or DUPKEYS control statement and an E32 exit cannot be specified with FIELDS=COPY. All Phase 3 exits can be used.
