Notes:
- The WRITE operation is not valid for a program-described
file used with a format name.
- If the EXFMT operation is used, the file must be externally
described (an E in position 19 of the file description
specifications).
- For subfile record formats, the UPDATE, CHAIN,
and READC operations are also valid.
