It wouldn't have to be an "internal change". As you implied, it would be quite satisfactory simply to have an alternative set of functions in addition to the ones currently available. However, because access to structures is so fundamental to (and pervasive in) programs that make non-trivial use of those structures, there could be a *substantial* performance penalty to writing and using mezzanine-like wrappers whose main raison-d'etre was adding or subtracting one. If RT were to offer these capabilities without performance penalty (e.g. as additional natives) that would solve the problem nicely. As for the agonizing length (and temperature) of the discussion, I must confess my own measure of bafflement. My experience in dealing with technology vendors goes back to the early 70's, when I was a subgroup officer in CUBE, the international users' group for Burroughs computers. We (the users' group as a whole) had very good experience with the kind of dialog in which we explained our problems, limitations, or difficulties, and the appropriate technical and/or product management folks would respond with suggested work-arounds or descriptions of new features which they would implement to provide solutions. These dialogs took place on a regularly-scheduled basis, and were taken seriously by all parties. (Since this was before the wide-spread availability of the Internet, the process took place via meetings scheduled every 6 months. ;-) It was quite common for Burroughs to provide better (faster, more efficient, more elegant, etc.) solutions than those originally proposed or suggested by the users. All in all, the process was highly satisfactory. -jn- ___________________________________________________________________ The purpose of computing is insight, not numbers! - R. W.
