The While...Wend statement syntax has these parts:
Part
|
Description
|
condition
|
Required. Numeric
expression or string expression that evaluates to True or False. If condition
is Null, condition is
treated as False.
|
statements
|
Optional. One or more statements executed
while condition is True.
|
Remarks
If condition is True, all 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.
The Do...Loop statement
provides a more structured and flexible way to perform looping.
Example:
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.
Dim
Counter Counter = 0 ' Initialize variable. While Counter < 20 ' Test value of Counter. Counter = Counter + 1 ' Increment Counter. Wend ' End While loop when Counter > 19. Debug.Print Counter ' Prints 20 in the Immediate window. |
