It should be easy to make a primitive in Forth then to do it, right? (I have a 75C that someone gave me, pretty beat up and lacking the battery pack and manuals, and I never learned to use it. I did use my 71B heavily in the late 1980's, but never learned its assembly language.)

That's the way I see C. An absolute disaster.

I don't understand either of these comments, both C and Forth provide plenty of constructs for for structured programming, however neither one of them forces you to use them.
