X-Y Coordinate Grid
Numerous commands refer to a screen grid with coordinates based on an inter nal
grid that is 2Ø48 x 2Ø48 units. The grid can be absolute, covering the entire
screen area, or relative to a current position. The absolute grid coordi nate of
ØØØØØØØØ is at the upper-left of the screen. The grid coordinate of

negative numbers to indicate positions above or left of a current position. In the
