SOME
SIMPLE

PROGRAMS
Type this program exactly as it appears here. Don't leave out the
numbers at the beginning of the line, since they are the line numbers
that tell the order that the lines of the program are implemented by your
computer. Be sure to press the RETURN key at the end of each line
you type.
10PRINT"PLUS/4"
This line tells your
computer to PRINT
Plus/4 on the screen.
20 GOTO 10
RUN
This line tells your
computer to go back
to line 10 and print
Plus/4 again.
This commands your
computer to carry out
what the 2 lines tell it
to do.
Press the RUN/STOP key to stop the program.
Why did your Plus/4 print its name so many times? GOTO tells your
computer to go back to line 10 and PRINT Plus/4 again and again.
This repetition is called a loop.
Now type this:
NEW RETURN

The computer responds:
READY.
Here you tell the
computer to forget
the last program
and get ready for
a new one
You DONT type this;

tell you it's READY
fora new program.
