        in various ways.        Anyway, one thing I've been trying to do all
        semester, just to 'spruce up' the  screen output, is to CLEAR the
        %^&$%$%^ SCREEN from modula!!!

        By the way, I'm using the 'mod' compiler on a vax under unix 4.3.


I don't think it's provided in standard modula, not to matter, what you have to
do is to write an esc sequence (i.e <esc>something) the something will depend
on the terminal type you're using. I'd guess you're using vt100s so the best
thing would be to simply ask your computer center if you could have a look at
the ref. manual for the type of terminals you use there.

you'll have to write somethin like;

writechar (chr(27));
writechar (chr(aa));

Can't remember the exact esc sequence.

As a matter of interest, do DEC provide anything like VMS's SMG screen handling
routines for Ultrix?????
