As far as I know, there are NO screen directives defined in F77.  If you want
to draw on a screen (other than using it as the default printer), you would
probably have to make use of system calls that are linked into your F77 program
by the loader/linker.

The only other possible exception is if the carriage-control character of '+'
(a plus sign) is supported for the screen.  On a paper printer, the '+' says
don't do a newline, only a carriage-return.  Experimentation with the '+'
should be able to tell you if it will foot the bill.
