I may misunderstand then. I thought that a library stack was enabled with the start using command, and that this is why the scripts run, because the stack script of a stack in use is inserted into the backscript. Am I wrong? If so, then how are the commands and functions in a library stack inserted into the message path?
I don't know if it's changed since the old MetaCard days, but back then Dr Raney explained one of the distinctions to me.
Stacks in use place their stack script into the message hierarchy just before the Home stack script. (In a standalone, Home is your mainstack.) This retains compatibility with HyperCard.
Scripts inserted "into back" are placed after the Home stack script; they are the last thing before the engine gets messages.
Another distinction is that any script of any object can be inserted into back (which allows a great deal of flexibility; the LiveCode IDE inserts button scripts into back to load things it needs.) But when a stack is put in use, only the stack script itself is inserted into the hierarchy; no other object scripts are available.
Libraries are strictly stacks in use. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
