comeau didn't compile it either.
I have no other compiler then gcc right now. my other compilers are so old they 
are useless.
however, I am reworking the code to use indexes instead. it's harder and more 
error-prone because I don't remember how the code works. I still think c++ 
should have iterator references or some kind of ability to pass iterators back 
through a function to save us all headaches. I consider that basic 
functionality. :-(

thanks for the pointers though. :-]
