In the case of UW, I gave up on Megamax C just after I distributed
version 3.4.  I was readying a newer version (basically just an LSC
version of 3.4, since I've been very busy with other things) when
I read about LSC's use of BSET, BCLR, etc. for resource attribute
changes.  I have MPW but I really don't want to convert UW again.
It is frustrating that I tried very hard to conform to Apple's
guidelines, but users of my program will get burned because of
compiler/runtime implementation decisions that were beyond my
control (and outside of my knowledge).

I find it difficult to fault Apple in this particular case, but I
do believe that they've been less than helpful with respect to
some other changes in the newer systems.  A case in point is the
handling of "dead" keys -- the official policy seems to be that
there's no way to do this.  There was a way to do this, and
MacTerminal used it (among others, of course), and it was a useful
thing to do, but the fact that it was a commonly-used feature
did not prevent the implementation from changing for ADB keyboards
(and perhaps for all keyboards in System 4.1; I don't have that yet).
I wouldn't care about KeyTrans and Key1Trans and Key2Trans if only
Apple had provided a trap which would enable/disable dead keys.

Perhaps some of this will be addressed in future tech notes;
unfortunately, there is a substantial time lag between the
introduction of new software and the documentation of its changes.
