Well, it isn't a while, but...
repeat
...
until <cond>
which has the situation that it exits when <cond> goes true, whereas
while <cond>
...
wend
continues looping on a true <cond>.
And /neither/ structure really handles the form where you need a bit
of processing before you can do the test...
loop
preprocessing which sets flag
exit when <cond>
other processing
end loop.
Using just a while loop, as in many languages, the above turns into:
(initial) preprocessing which may set flag
while not flag
other processing
preprocessing which sets flag
wend
