/[NO]IDENTIFY

   Determines whether to display the input file name before performing
   extraction upon its contents.  By default, the file identification
   is performed if the input file specification is a list of files,
   contains any wildcards, or includes a search list.  /IDENTIFY forces
   identification; /NOIDENTIFY suppresses identication.

   Note:  the file identification is written to the same destination as
   the extracted data, so it should normally be suppressed if the data
   is being translated into EBCDIC or if vfc-headers are kept.
