[REBOL] Re: Troube Calling Function within Object

USAGE:
BIND words known-word /copy
DESCRIPTION:
Binds words to a specified context.
BIND is a native value.
ARGUMENTS:
words -- A block of words or single word. (Type: block word)
known-word -- A sample word from the target context. (Type: word)
REFINEMENTS:
/copy -- Deep copies block before binding it.
known-word
must be a word which was defined within the same scope as when
you defined the 'player word. The problem then becomes one of finding this
word. For example:
; --------- START CODE -----------
player: make object! [
; Really this only sizes the block, ignoring the first element
find-records: func [arg [block!]][return length? arg]
]
known-word: none
some-func: func [table [string!] request [block!]][
bind some-word: to-word table 'known-word
return do get (in get some-word 'find-records) next request
]
print some-func "player" ["garbage" "b" "c" "d"]
;-------- END CODE ---------------
Good thing I tested this - not quite as straight forward as I thought, but
do-able.
As long as you define 'player in the global context, it should be easy to
find another word to 'bind with.

Michael, I get the concept of converting the string "player" to a word, but
how do I bind it to the actual player object?
Thanks!
Jamey.
