Re: Separated headers

I have recently cross-compiled my first forth system (subroutine threads),

looks like this:
[link][flags][count][name] code
I guess I need one more pointer in the header like this:
[link][flags][count][name][code_ptr] which will connect header to
definition.

Questions:

1. What is the best way to handle allocation in name dictionary? My current
thought is to revector dp with words like:
PROGRAM HERE ( returns dp from program code dictionary)
NAMES HERE ( returns dp from name dictionary)

2. Implementation of word >name is trickier. It appears that >name now
should use FIND to go back to name field.

Are there any other pitfalls that I should pay attention to when doing this?
Any advices an comments appreciated.
Best regards,

you dont need to use find to locate a word header when you separate
headers from code space, isforth does this and >name is basically
defined as : >name 4- @ ; because i store an NFA pointer at CFA -4.
the trick is when you do headerless words this pointer has to be
cleared or it will point to bogus data!
