Hi Robert,

On Tuesday, August 27, 2002, 8:20:56 PM, you wrote:

This  way  you are copying and rebinding the blocks at each cycle.
Using functions is probably the best way, but if you prefer blocks
you can:

   predicate: bind/copy predicate 'list
   action: bind/copy action 'list
   forall list [
       object: first list
       if do predicate [do action]
   ]

Regards,
   Gabriele.
