programming delays.

[durrieu@tantale.cert.fr (Guy Durrieu)]

In my program transformation tool, I would like to include an automatic mode
in which:

- transformations are read from a file.

- for each transformation:

               - the target is highlighted.

               - a delay occurs.

               - the transformation is performed.

I can do each of these sub-operations, but I don't succeed in doing them  in
the above order. Whatever I do, the delay occurs first, then the highlighting.
However I specify first the redisplay and then the delay. I suppose there  is
a problem of communicating processes...

Any help would be appreciated!
