EXAMPLE
NEW
The
NEXT statement is used with a FOR statement to form a
repetitive section of a program .
CONFIGURATION
NEXT X
A
FOR statement begins a loop , and a NEXT statement ends it.
The FOR statement sets an initial value and a final value for the
counter. The optional STEP statement specifies the amount that
the counter is increased or decreased each time the loop is
executed.
EXAMPLE
10 FOR I = 1 TO 10 STEP 2
20 PRINT I
30 NEXT I
In the previous example, the variable I is the co unter. The initial
value of the counter is 1, and the final value is 10. The value of the
counter is increment ed by 2 each time the loop is executed.
The section
of the program between the FOR and NEXT
statements is repeated for each different value of the counter .
Each time the NEXT statement is executed, the value of the
counter is changed by the STEP argument value. The loop is
repeated for each value of the counter. In the previous example,
the loop is repeated 5 times, with the counter equal to 1, 3, 5, 7,
and 9. The initial value of the counter (I) is 1, and it is increased by
2 each ti me the loop is executed because of the STEP 2 statement.
