[statements]Wend
The While...Wend statement syntax has these parts:
|
Part |
Description |
|
condition |
Numeric or string expression that evaluates to True or False. If condition is Null, condition is treated as False. |
|
statements |
One or more statements executed while condition is True. |
If condition is True, all statements in statements are executed until the Wend 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 Wend statement.
While...Wend loops can be nested to any level. Each Wend matches the most recent While.
Tip The Do...Loop statement provides a more structured and flexible way to perform looping.
Do...Loop Statement, With Statement.
This example uses the While...Wend statement to increment a counter variable. The statements in the loop are executed as long as the condition evaluates to True.
Counter = 0 ' Initialize variable.Counter < 20 ' Test value of Counter.
Counter = Counter + 1 ' Increment Counter. ' End While loop when Counter > 19..Print Counter ' Prints 20 in Debug window.
