Data Bindings
----------------------------------------------------------------------
1994.08.29

I had attempted to add bindings to this library once before and became
confused with how I should approach this so I scrapped it at that
point in favor of getting a beta version ready.  Talked to Scanner
recently and we both agreed that the binding was necessary and while
I don't think the same questions exist in my mind there are certainly
other ones which do.

There is a small conflict regarding traces.  When we setup a write
trace we were able to receive a trace whenever a write occurred to a
variable.  Problem is that the set function writes the data so it
ended up calling its own trace routine ; so we added a mechanism to
disable the trace mechanism.
