WHILE Statement

Executes a series of statements as long as a given condition is TRUE.

Syntax

WHILE condition

   [statements]

ENDWHILE

condition                Expression that evaluates to TRUE or FALSE.

statements                One or more statements executed while condition is True.

If condition  is TRUE, all statements are executed until the ENDWHILE statement is encountered. Control then returns to the WHILE  statement and condition is again checked. If condition is still TRUE, the process is repeated. If it is not TRUE, execution resumes with the statement following the ENDWHILE statement.

Unlike the FOR statement, the WHILE statement evaluates condition on every loop pass.

Example

VARIABLES: a TYPE: Integer

WHILE  ( a > 0 )

   print "a = ", a

   a = ( a - 1 )

ENDWHILE
