5.3 Commands for Looping Structures

Looping structures repeat a block of statements, either for a specified number of times or

until a certain condition is matched. In BASIC, two kinds of looping structures,

FOR...NEXT and WHILE...WEND can be used. Command EXIT can be used as an

alternative to exit from both FOR...NEXT and WHILE...WEND loops.

Both FOR...NEXT and WHILE...WEND statements can be nested up to 10 levels.

EXIT

Purpose

To provide an alternative exit for looping structures, such as FOR...NEXT and

WHILE...WEND statements.

Syntax

EXIT

Remarks

EXIT can appear anywhere within the loop statement.
