This completes loading of the BASIC program. You can talk to the computer using BASIC, and the
computer will respond.
1.3.3 Try Executing a Program
Loading BASIC into the computer doesn't cause it to do anything; first, it must be given instructions
in BASIC as to what it is to do. Although we will not explain the instructions of BASIC until later, let's
go ahead and try executing a BASIC program right now.
Remove the cassette tape from the recorder and turn it over so that the "B" side is up. A sample
program is recorded on this side of the cassette tape. Using the following procedures, load this program
into the computer and execute it.
(1)
After turning the tape over and reloading it into the recorder, press the REWIND button to
rewind it. Next, type in
[Q[Q][AJIQ)
and press the
I CRI
key; when the message
.!.
PLAY is display·
ed, press the
I
PLAY
I
button on the data recorder. This begins loading of the sample program.
(2) When loading is completed, the cassette tape stops, READY is displayed on the screen, and the
cursor starts to blink again.
(3)
Now that the program has been loaded into the computer's memory, try executing it. This is done
by typing in
[B][!l)~
and pressing the
I
CRI
key.
(4)
Now let's take a peek at the program. Hold down the
I
SHIFT
I
key and press the
I
BREAK
I
key. This stops program execution and displays the words BREAK and READY, then the cursor
starts to blink again.
(5)
Type in
[11[][§][!]
and press the
I
CRI
key. This lists the lines of the program on the screen one
after another. (Output of the list can be temporarily stopped at any time by pressing the space
bar.)
(6) If you wish to resume program execution, type in
[B][!l)~
again and hit the
I
CRI
key.
(7) If you want to run a different program, set the cassette tape containing that program in the
recorder, LOAD the program, then RUN it. The previous program is automatically erased from
memory when the new one is loaded, so the computer contains only the BASIC language and
the last program loaded.
