Right. Perhaps: o There's a property that controls what subs can do with a lexical variable. I'll call it Yours. o By default, in the main package, topics are set to Yours(rw); other lexicals are set to not Yours. o A mechanism exists for a sub to bypass this access control for use with library routines. -- ralph
