Syntax:

WHILE conditionalexpression

[statementblock]

WEND

Description:

A WHILE...WEND continues to execute statementblock as long as the con-

ditionalexpression

is true (not zero) according to the steps below.

(1) The conditionalexpression in the WHILE statement is evaluated.

(2) If the condition is false (zero), the

statementblock is bypassed and control

passes to the first statement following the WEND.

If the condition is true (not zero), the

statementblock is executed. When

WEND statement is encountered, control returns to the WHILE statement. (Go

back to step (1) to be repeated.)

• The WHILE and WEND cannot be written on a same program line.

• If no

WEND is written corresponding to the WHILE, a syntax error occurs.

• The BHT-BASIC does not support a

DO…LOOP statement block.

• You can nest the WHILE...END statements to a maximum of 10 levels.

• When using the

WHILE...WEND statement together with block-structured state-

ments (DEF FN...END DEF, FOR...NEXT, FUNCTION...END FUNCTION,

IF...THEN...ELSE...END IF, SELECT...CASE...END SELECT, SUB...END SUB,

and

WHILE...WEND), you can nest them to a maximum of 30 levels.
