You must get rid of two ideas that are in the basic/lisp/c world.
1. You don't need dynamic strings. Just keep track of where you left them.
[ If you really need them, don't do circular buffer or string stacks.
Interface to the memory wordset (ALLOCATE c.s). ]
2. Zero ended strings is a stupid 60's c-cludge. Copying that into Forth is
beyond .. . They can't accomodate zero byte in strings, They cannot
accomodate multiple byte characters.
If you fetch a string, you have a "c-addr count". Forth can have 2 items
on the stack you know.
So In my CP/M day I get by with $! $@ $+! and $C+! .
I made a program playing a text adventure game with that.
