What is Memory Capacity?
The personal computer memorizes your drawings in their order as a
program. This function provides for program display and program
save. If the drawings are too complicated, however, the computer may
fail to do it. The memory capacity display on tne upper left or upper
right of the screen indicates how much can be st Umemorized.
When the capacity becomes short, use the screen save function to
clear the screen and reload the illustrations. The memory capacity
display shows 7777 and you can continue iilust rating. Note, however,
that the order of drawing is not programmed. So the background
color, dotted screen, program display, redisplay, BASIC save, program
save, erase, and some other commands can not be used.
