This week I received CFORTH, a forth written in C, from
Mark Seiffert (thank you!).

It turned out, that CFORTH is a 16-bit forth, i.e. integers
ar 16 bit wide and characters are stored one per word,
leaving one character per word free.

Now, I want to port it to an environment where integers and
addresses are 32 bit wide (since I want to address all of the
memory in the machine).

Since I am not familiar with 32-bit FORTHS, I have some
questions:

o  Does a 32-bit FORTH imply that a 16-bit data type is not
   available?

o  How are 16-bit loads & stores implemented?
   (perhaps S! and S@ ?!)

o  How are character strings stored in memory?
   (4 characters per word, or 1 character and 3 chars free)


o  Is there any standard for 32-bit FORTHS out there?

So long
