Re: Speed Question...

I've never used a C array to store (id)'s, is that possible and is that
what you are meaning?

As I said in the first email, I am using NSelect to choose 5 locations from
an emptySpacesList.  NSelect puts the locations into a list.  So, if I
understand your suggestion, I would need to then copy that short list into
a C array?  My gut reaction is again to wonder whether that step would cost
more than just using the atOffset?
