So I can't think of anything to stop a > vforth from being written... unless the vforth name has already been used. I took a look at a C Forth implementation, pForth. I'm not sure I follow everything he is doing, I guess my C is a bit rusty. I see he used a large CASE statement for primitive words. I'm not clear on how the inner interpreter works through the XTs in a word definition for words compiled into other words. I suppose it is just a matter of indexes into the dictionary (or pointers in C) but I don't see the code he is using to manipulate them. He uses a ton of defines which hide the details and it is a bit of work for me to try to figure this out. I'll get it sooner or later. I just need to keep reading. -- Rick C
