Subject: [REBOL] context exploration
Hello,
While playing with contexts, I threw together this little function to show
the words that are defined in a context (and their values in that context).
(something like that have been discussed before AFAIR, but a 1min. search
didn't find it, sooo :-)
It goes like this:
show-context: func [word [word!]] [
foreach x-word next first system/words [
if value? bind x-word :word [
print [:x-word "|" get bind x-word :word]
]
]
]
Attached is a script that demonstrates the use of the function with contexts
created with func, use and make object!
Best regards
Thomas Jensen

Hello,
forgot to say, that words that have the special value unset! will not be displayed.
