All of this reminds me of trying to do the table-creation/lookup in Pascal (on proprietary equipment, so the language was chosen for me). I had to create index arrays for each dimension, and I had to make it generic enough so when a breakpoint changed, I only had to update one number (and the breakpoints changed daily). It was all a big mess of brackets and parens.

In fact, it was so ugly (even after max beautification), I felt I had to write a 2 paragraph explanation for the single line table population statement. And then added a "Don't touch this unless you know what you're doing. In fact, just don't touch it, because you don't know, and you don't need to."

I wonder if that code is still there?
