I wonder if your code has to use !! at all? I took a look at a random module from the above link, and (without making much attempt at understanding it), I'd guess that using accumArray and friends would be more appropriate. Mostly you don't want to be doing indexing on lists.

Thanks for everyone's suggestion. Don Stewarts tools seems to be most appropriate for me. Most of the !! are used to access a list of parameters similar to accessing structures in C. I am not particularly sure how to apply accumArray for something like that? I will go through the accumArray documentation and see how I might apply them. thanks again. fernan -- http://www.fernski.com
