RECL

 RECL = rcl

 rcl  Is a scalar integer variable 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 assigned value is expressed in longwords (4-byte units) if the
 file is currently (or was previously) connected for unformatted
 data transfer; otherwise, the value is expressed in bytes.
