CROSSHATCH

This short "AstroBASIC" program draws a crosshatch pattern to the Bally's 
screen using the '#' marks.  The program was written so that a digital 
camera can be pointed at a TV screen to take pictures (screenshots) and 
videos.  The pattern helps to focus the camera and check for level, as well 
as to center the TV in the frame.
