   8         (get_internal_unit): Use LEN_TRIM to shorten selected internal
   9         unit strings for optimizing READ. Enable this optimization for
  10         formatted READ.

  49         "mode" to signify that raw output is to be used vs output with
  50         delimiters. If the mode is set to DELIM (1) proceed with

  52         only if a delimiter was previously specified. Update the call to
  53         write_character with the mode argument given.

  56         semi-colon or comma correctly only when needed with using
  57         delimiters. Cleanup whitespace.

  59         default to using quotes. Get rid of the tmp_delim variable and
