ever, in most prepackaged programs, the STOP
function of the RUN/STOP key is intentionally
disabled (made unusable). This is done to pre
vent the user from trying to stop a program that
is running before it reaches its normal end point.
If the user were able to stop the program, valu
able data could be lost.
Restore The RESTORE key is used with the RUN/STOP
key to return the computer to its standard condi
tion. To do this, hold down the RUN/STOP key
and press RESTORE.
Most prepackaged programs disable the
RESTORE key for the same reason they disable
the STOP function of the RUN/STOP key: to pre
vent losing valuable data.
CLR/Home CLR stands for CLeaR. HOME refers to the
upper-left corner of the screen, which is called
the HOME position. If you press this key by itself
the cursor returns to the HOME position. When
you use the SHIFT key with the CLR/HOME key,
the screen CLeaRs and the cursor returns to the
HOME position.
Commodore Key The C* key (known as the COMMODORE key)
fr has a number of functions, including the follow
ing ones:
1. The C* key lets you switch back and forth
between the upper/lower-case character
set (which displays the letters and charac
ters on the top of the keys), and the upper
case/graphic display character set (which
displays capital letters and the graphics
symbols on the front face of the keys). To
switch modes, press the O key and the
SHIFT key at the same time.
2. The G key also lets you use a second set of
eight colors for the cursor. To get these col
ors, you hold down the O key while you
press a number key (1 through 8) in the top
row.
