Graphics
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.
