The reassigning command

The SQ has a command that allows you to change the graphics option assigned to any of the four individual graphics options commands.

The command looks like this:

ESC ? s m

The letter s represents the command that you wish to change the assignment for (K, L, Y, or Z) and m is the number of the graphics option that you want to assign to it. For example, to change the ESC K command to use the CRT I graphics option, the command in BASIC is:

LPRINT CHR$(27>;“?“;“K”;CHR(4)

This is a quick way to change the aspect ratio of the design that you are printing. Changing the graphics option will change the width without changing the height. You should, however, make this change with caution.

If you change one of the S-element graphics options to a

24-element graphics option without changing the program that supplies the graphics data, you will print garbage if the program prints at all. Remember, the 24-element graphics options require three times as much graphics data as the S-element graphics options.
