LOOPING
A loop is a set of one or more instructions.
These instructions can be repeated as many
times as you want.
You can create a loop with a
GOTO
statement.
A program like the following will run continually:
10
INPUT “GIVE ME A NUMBER”;N
20
PRINT “YOUR NUMBER IS”;N
30
GOTO 10
RUN
You can modify the program to get out of a loop by using an
IF
statement to control the
loop like the program that calculates the area of a rectangle.
Another way to create a loop is through the use of the
FOR
and
NEXT
statements.
These
statements surround the instructions that you want to repeat.
For example, type the following
:
NEW
10
FOR N=1 TO 10
press
ENTER
20
PRINT “HELLO”
press
ENTER
30
NEXT N
press
ENTER
RUN
The word “
HELLO
” appears 10 times on the screen.
You can change line 20 to print
the value of N every time the loop repeats.
Type
:
20
PRINT “N IS”;N
press
ENTER
