While~WhileEnd
Syntax: While 䡺 <expression>
[<statement>] …
WhileEnd
<expression> is a condition that evaluates to true or false.
Function: The specified statements are repeated as long as the condition is true.
Description
• The statements between While~WhileEnd are repeated as long as the condition is true.
When the condition becomes false, execution jumps to the next command after the
WhileEnd command.
•Since the condition comes after While, the condition is evaluated before the loop is started.
•You can use a multi-statement command (:) in place of the carriage return to separate
statements.
• It is always a bad idea to use the Goto command to exit a While~WhileEnd loop. Not only
is it poor programming, it can cause problems due to improper termination of internal
processes used by the loop operation.
