I just finished transcribing this from the scanned PDF, and thought it might be interesting to others. It certainly took me back! I was really into Forth as a teenager (thanks to my dad's interest), and wrote several of my own Forth compilers [1]. It's a unique and interesting language, though most Forthers spend too much time writing their own compilers and being language zealots instead of getting things done. It's hard to believe anyone could think the Search-Table code in Figure Five is sane. There's more stack-effect tracking than code!<p>[1] For example, "Third", a 16-bit self-hosting Forth compiler for DOS: <a href="https://github.com/benhoyt/third">https://github.com/benhoyt/third</a>
