The short answer is that it is not possible, since if you are
doing any processing, you are not receiving events.
However, what you can do is doing a bit of processing, then
waiting a bit for events, then doing another bit of processing,
and so on. In this case, you'd need a loop, because you want to
exit from the WAIT every so often so that you can do your bit of
processing.
For example:
forever [
wait 0 ; this does not actually wait, but allows the
; processing of events that have already happened
; if you don't want to be processing all the time,
; you might want to wait more.
do-some-processing ; here you should do a little step of
; processing; while you are doing this,
; you are *NOT* processing events, so this
; step should be as quick as possible.

Gabriele.
