Do While has the following syntax and allows you to code a pre-test and
post-test loop. It also allows you the option to exit from the loop 
before the loop test condition becomes true.
Do [{While | Until} condition]
    [statements]
    [Exit Do]
    [statements]
Loop
Or, you can use this syntax:
Do
    [statements]
    [Exit Do]
    [statements]
Loop [{While | Until} condition]
Do Until is essentially the same thing except that the logic for the
condition is reversed.
The While Wend syntax only allows a pre test loop and does not allow you 
to make an early exit from the loop.
While condition
   [statements]
Wend
