Syntax:

FOR controlvariable = initialvalue TO finalvalue [STEP

increment]

NEXT [controlvariable]

Parameter:

controlvariable

A non-array numeric variable.

initialvalue, finalvalue, and increment

Numeric expressions.

Description:

FOR…NEXT defines a loop containing statements (which is called "body of a loop")

to be executed by the number of repetitions controlled by initialvalue,

finalvalue, and increment.

■ Processing procedures

(1) The Interpreter assigns initialvalue to controlvariable.

(2) The Interpreter checks terminating condition; that is, it compares the value of

controlvariable against the finalvalue.

- When the value of increment is positive:

If the value of controlvariable is equal to or less than the final-

value

, go to step (3). If it becomes greater the finalvalue, the program

proceeds with the first line after the NEXT statement (the loop is over).

- When the value of increment is negative:

If the value of

controlvariable is equal to or greater than the final-

value

, go to step (3). If it becomes less than the finalvalue, the pro-

gram proceeds with the first line after the NEXT statement (the loop is over).

(3) The body of the loop executes and the

NEXT statement increases the value of

controlvariable by the value of increment. Then, control returns to

the

FOR statement at the top of the loop. Go back to step (2).

Flow control statement

FOR...NEXT

Defines a loop containing statements to be executed a specified number of times.
