Yeah, drew, What exactly do you want it to do?

Example spec: I want the arrow keys to write X's anywhere on the screen, starting with row 1 column 1.

Example spec: I want the arrow keys to write X's in the range Row 10 Column 10 to Row 20 Column 70 starting with Row 12 Column 40 .

With no specs, we can't say it does or does not work. It certainly writes X's via the arrow keys in QBasic 1.0.
