I once used Forth. At first it appeared like a really neat way to make an instant program. :omg: Just like using my favorite HP RPN calculator which I still love. :) Forth has/had 2 stacks which added to the confusion.:confused: Problem was, you made a great bit of code that worked, and 2 days later could not understand or enhance your program. It became gibberish. :(( HP calculator program has same problem, but for a transient program application like an instant vector rotation or weird conversion it is great. It just can't speak or spell, and neither can I. C,C++,Delphi,VB are easier to maintain. :) With .asm at least you can make an instant 400MHz data analyzer with a printer port, sans Windows.:suss:
