To create a zero terminated string in RetroForth you do:
" a string" zt-make
zt-make ( a c -- a c ) takes a counted string, and returns a zero
terminated one (allocated at HERE) with a length of C
zt-free ( c -- ) frees up the space allocated for the zero terminated string
I don't have any dynamic memory allocation in RetroForth, but the
zt-make/zt-free solution works quite well.
