Is there a reason that you're not using the in-built debugger for this? I'm fairly sure it would make your life much easier.
I'm making code that will associate a value with a function name and will store both in a table. Thank you Mark and Stefan for helping.
It sounds as if you're working with Forth at quite a low level. Perhaps you should consider breaking the task down into small chunks and then posting patches to the list for feedback? Then people can offer more guidance to help you.

This is what I am trying to do. I am making a word called '{' that will read each symbol after it and load it into memory. Here is my code so far:
variable currentWordAddr variable currentWordLen
/ copies the current words name / must be called at beginning of '{' word : copyWordName ( - addr len) ib >in @ dup alloc-mem swap 2dup
r r
move r> r> currentWordLen ! currentWordAddr ! ;
: { copyWordName begin parse-word dup 0> while 2dup drop " }" comp 0= if exit then 2dup drop " ;" comp 0= if false useTopStackValue ! else currentWordAddr @ currentWordLen @ loadLocalVariable then repeat does> copyWordName ; immediate
copyWordName simply copies the word name that comes before the '{' and after the ':'. I am trying to make the '{' word have a compile-time behavior of loading each symbol after the '{'. It stops when '}' is encountered. So if this word is being compiled : hi { dog cat hamster } the '{' word will send dog, cat, and hamster to loadLocalVariable. At run-time, it should only call copyWordName to load the current word being ran.
I simply don't know how to do both compile and run-time behaviors that I want. Anyone know how to do this? This is my starting point for local variable support in OpenBIOS.
