  RECL = rcl

  rcl  Is an integer scalar memory reference whose value
       depends on the following conditions:

       - If the file or unit is open, "rcl" is the maximum
         record length allowed in the file

       - If the file is not open, "rcl" is the maximum
         record length allowed in the file; or, if the
         maximum record length is 0, "rcl" is the length
         of the longest record in the file

       - If the file is segmented, "rcl" is the longest
         segment length in the file

       - If the file does not exist, "rcl" is 0.

  The length is expressed in bytes for formatted files and longwords
  for unformatted files.
