You have a a: context[ b: 2 c: 3 : d: 4] You have a block of words, like block: [b c d] And you want this words looked up in this context. similar to a/b a/c etc. Then you say bind block in a 'b And now all words in the block are bound to 'a. (words not in 'a are unchanged.) So get first block returns 2. Note you give a reference-word in a context, not the context itself. that way you can also bind to function-argument, where you don't have a context-handle. (with newer betas for 1.3 you can also give the context directly, like bind block a ; instead of "in a 'b" or "in a 'self" ) This ist most usefull to execute code in a context, say you want to execute it using a special set of functions. Most of the time you are using 'bind implicitely, as 'func and "make object" use it automaticly. sometimes you want that feature without funcing or making, then 'bind can rescue you. > TIA > > ==christophe -Volker -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.
