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