The following works on Linux (actually, Debian test):
$ cat steinke.f
CALL SYSTEM('clear')
END
$ g77 steinke.f
$ ./a.out
<clears screen>
So it basically works. Now why it doesn't work on Windows is beyond me,
but I have to work daily with people who use Windows and most of what is
happening to them is incomprensible (both by them and by me).
