You wanted to type the word ERROR, not
ERROER. To delete the incorrect E that pre
cedes the final R, position the cursor in the
space where the final R is located. When you
press the DEL key, the character to the right of
the cursor (the R) automatically moves over one
space to the left. You now have the correct
wording like this:
PRINT "ERROR"
Using INSerT and DELete Together
You can use the INSerT and DELete functions
together to fix incorrect characters. First, move
the cursor to the incorrect characters and press
the INST/DEL key by itself to delete the charac
ters. Next, press the SHIFT key and the INST/
DEL key together to add any necessary space.
Then type in the corrections. You can also type
directly on top of undesired characters, then use
INST to add any needed space.
The Control key is used with other keys to do
special tasks called control functions. To per
form a control function, hold down the Control
key while you press some other key. Control
functions are often used in prepackaged soft
ware such as a word processing system.
One control function that is used often is setting
the character and cursor color. To select a color,
hold down the CTRL key while you press a num
ber key (1 through 8), on the top row of the key
board. There are eight more colors available to
you; these can be selected with the Cf key, as
explained later.
This is a dual function key. Under certain condi
tions you can use the RUN function of this key
by pressing the SHIFT and RUN/STOP together.
It is also possible to use the STOP function of
this key to halt a program or a printout by press
ing this key while the program is running. How-
