Thanks for clarifying! In that case, he and I have the same "problem" although at very different levels. I've written in other posts about Forth and Lisp that I would very much like to get over the hump of changing how I think about problems. Unfortunately, I have never been able to do it. There are times where I see how Moore and McCarthy are using a language to define itself. I can sort-of understand how Moore creates a custom language in Forth to tackle something. But, damned if I can explain it or apply that to even a toy problem. I am thankful that there are people out there who can think differently.
