   (defobfun (do-scroll *scroll-bar*) ()

   (defpascal scroll-proc ((my-control :ptr) (partCode :word))

   Why does this work?  Why doesn't scroll-proc have
   to (ask <somebody> (do-scroll))?

The scroll-proc is only called after a DIALOG-ITEM-CLICK-EVENT-HANDLER
passes things to the ROM.  The click-event-handler is a *scroll-bar*
obfun.  So, at the time the call-back happens, the scroll-bar is
still the current object.
