Yeah I understood that and was just mentioning that Forth back then
didn't have locals like now.  I don't remember if the Thinking Forth
dialect had wordlists.

Thinking Forth quoted Chuck saying to allocate true globals in the
initialization screen, and pseudo-locals in the same screen where they
were used.  Back then the program and data were both held in ram, so if
you had a chunk of code that needed a temp variable, you could probably
afford a permanent ram cell since its ram consumption was much smaller
than the code's.

These days on MCU's, ram is often considerably more scarce than program
memory.  So allocating permanent ram for variables needed only
temporarily is even less pleasant than before.

With today's larger programs things get out of control more easily, but
when the program is small enough, using globals like that is manageable.
