Example
An X-Y plotter can write text at any position within its working envelope. Indi-
vidual characters are defined as a sequence of moves relative
to a start point. Therefore, the same commands can be used regardless of the
plot origin. The command subroutine for the letter M is:
write_m:
MOVE(0,12) 'move A > B
MOVE(3,-6) 'move B > C
MOVE(3,6) 'move C > D
MOVE(0,-12)'move D > E
