Node: Default to Console I/O, Next: Labels Visible to Debugger, Previous: Better List-directed I/O, Up: Missing Features
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.
