Default to Console I/O
----------------------

   The default I/O units, specified by `READ FMT', `READ (UNIT=*)',
`WRITE (UNIT=*)', and `PRINT FMT', should not be units 5 (input) and 6
(output), but, rather, unit numbers not normally available for use in
statements such as `OPEN' and `CLOSE'.

   Changing this would allow a program to connect units 5 and 6 to
files via `OPEN', but still use `READ (UNIT=*)' and `PRINT' to do I/O
to the "console".

   This change probably requires the `libg77' project.
