CHAPTER 5
SOFTWARE
USING SOFTWARE
Now that you have practiced using the key
board of your VIC or 64, it's time to try load
ing your first commercial program into your
computer. Choose the program—either on
cassette or diskette—that you wish to prac
tice loading. Then, follow the step-by-step
instructions presented here. If you are using a
cassette program, follow the "ON CASSETTE"
instructions; if your program is stored on a dis
kette, follow the "ON DISKETTE" instructions.
FIRST, MAKE A BACKUP COPY
Even before you run your first program, you
should make a copy of it on a blank cas
sette or diskette. You can then use the backup
copy of the program and keep the original in a
safe place. This way, if anything happens to
the copy you are using, you will still be able
to use the original.
Many software companies have done some
thing to their cassette tapes and diskettes to
protect them from being copied for commercial
use. However, usually there is some method
available to you for making a backup copy. Do
not buy programs that cannot be copied for
backup purposes! If you already have a pro
gram that specifically says it cannot be copied,
your local users' group may be able to help
(see Chapter 6). Otherwise, be sure that you
can return a defective cassette or diskette pro
gram and exchange it for one that will work
correctly.
If no instructions are given for making a copy,
try the following set of commands to make
your own archival backup. (This right is
guaranteed to you by law.) If your program
cannot be copied and you want to practice
running it anyway, skip to the "NOW, RUN
THE PROGRAM" section of instructions.
ON CASSETTE
Inserting the Cassette
STEP 1
Turn on your computer, the TV, and the
Datassette or other cassette player.
STEP 2
Hold the cassette with the side you want to
use facing up and insert it into the Datassette
or other cassette player. Then, close the lid.
When handling the cassette, be sure not to
touch the actual magnetic tape.
NOTE: If this is the first time you are using this
cassette tape, do the following:
• Press the FAST FORWARD button on the
Datassette or cassette player and let the
tape run to its end.
• Press the STOP button; then press the
REWIND button to bring the tape back to its
beginning. This helps even the tension on all
sections of the tape so that it will work
smoothly and reliably.
Loading the Program
Into Memory
STEP 1
On the keyboard, type the word LOAD.
NOTE: Whenever you type instructions, if you
make any mistakes, simply use the INST/DEL
key to backspace and erase, or the
SPACE bar to move forward and erase.
STEP 2
Once the word LOAD is typed correctly, press
the RETURN key. The computer flashes a mes
sage on the screen:
PRESS PLAY ON TAPE
STEP 3
When this message appears, press the PLAY
button on the Datasette/player.
• IF YOU HAVE A VIC, the following message
will appear on the screen:
OK
SEARCHING
• IF YOU HAVE A 64, the screen will go blank
for a few moments. Then the following mes
sage will appear:
FOUND
To continue loading the program ON THE 64,
press either the C= key or the SPACE bar.
[ON THE NEWER MODELS OF THE 64, the
program will continue to load even if you
forget to do this.)
STEP 4
You will know that the program is loading
when:
• IF YOU HAVE A VIC, this message appears:
LOADING
READY.
- IF YOU HAVE A 64, the screen becomes
blank again.
