[REBOL] Re: bind
From: ryanc:iesco-dms at: 18-Oct-2001 12:30
Bind just tells rebol where to look for the definitions of words
in a block when they evaluated by the interpreter.
examples:
>> words: to-block {copy "test"}
== [copy "test"]
>> do words ; the words are not bound to any meanings!
** Script Error: copy is not defined in this context
** Where: do-boot
** Near: copy "test"
>> do bind words in system/words 'self
== "test"
>> do words ; bind is persistent too.
== "test"
>> words: to-block {copy "test"}
== [copy "test"]
>> meanings: context [copy: :alert] ; context is the same as
make object!
>> bind words in meanings 'self
== [copy "test"]
>> do words ; shows an alert box saying "test".
== true
>> ; Same as...
>> meanings/copy "test"
== true
>>
