Hi Lee, I can't believe that I have never seen this thread. I have suggested this lisp specifically for the EDITING functionality to a number of OPs.
I have not had occasion to use it, or rather haven't had a big enough batch of them at one time, since I first saw it, and so have not downloaded and run it.
This is very well thought out and really helpful, assuming that it does what it is meant to do.
I just noticed the INCREMENTAL REV function which is important, and very helpful.
Keep up the GREAT work!
I am further excited by the fact that you have tweaked this....... that does it! I'm downloading this little beauty and taking it around the block.
I haven't checked it yet, am hoping that the incrementation can be numeric or alphabetic. The way you described it, seems like it is only numeric.
Sometimes REVs are ALPHA instead of numeric.
