Well, I don't have a routine.  You could use Movax's horizontal line
function (just change it so it turns off pixels instead of on) and then
write a vertical line function (unless there is one already which is pretty
likely to exist) and then a box routine which combines the horz. and vert.
"white" lines.

I also have a question for you:  Are you related to the Rosenbergs who were
hung (only Americans to be killed in peacetime) for passing on nuclear bomb
information to the Soviets which in turn started the Cold War?
