Also, it is possible to create an alternative SAVE-SYSTEM word that will
generate image without SAVE-SYTEM support included (similar to MARKER word).

It would be great. I would like to have it in a standard distribution.
Only thing, in my original version I'm using alternative wordlists to hide
implementation details. For instance, S-record words enclosed in wordlist
definition like this:
GET-ORDER \ save current destination
WORDLIST WORDLIST-NAME SREC-WORDLIST \ create new wordlist
SREC-WORDLIST SET-CURRENT \ set it as destination list
GET-ORDER SREC-WORDLIST SWAP 1+ SET-ORDER \ add it to search order
[... srec words ...]
GET-ORDER NIP 1- SET-ORDER \ remove new list from search order
SET-ORDER \ restore original destination
As you can see, I'm using two words that are not part of your standard image:
WORDLIST and WORDLIST-NAME. Although they are could be easily defined, I'm
forced to load such definitions early.
You already have words like SET-ORDER, GET-ORDER, MARKER in pbForht image. Is
it possible to add those WORDLIST and WORDLIST-NAME words too?
I like the idea of wordlists a lot. It's an only way how one could hide all
unnecessary implementation details and keep global namespace clean. Including
them in the standard image would greatly support this technique.
Other little thing, I've remarked that MARKER word can't restore task chain.
It correctly removes the task definition, but doing nothing about the chain.
All the multitasker words already in the standard image. I think it would be
also nice if MARKER can take care about the task chain too.
What do you think?
Sergey
