Easier? Definitely. But what would be the fun of that? I had ulterior motives in this case, as there are some other potential uses of locals with those commands and I wanted to make sure I could get them to work properly before investigating those possibilities.

A couple of examples:

- Being able to quickly retrieve the "remnant" elements of a combination (those elements not currently selected)
- Being able to read/manipulate the "control object" for the permutation/combination, thus allowing the user program to "jump ahead" during processing in a controlled way

Enhancing what can be done by the user program object is a careful balancing act, though. The overhead involved with figuring out what to do with the control object could very well erase the benefit of having that feature. Everything that happens in that program object is repeated at the innermost loop level, so there's a steep price to pay for any inefficiencies.
