Yes, it is true: MPW 3.0 will have the new **feature** of the C compiler
using mixed case for true Pascal calling conventions, and all lower case
will supply the appropriate C glue for the C/P string stuff.

And yes it will require editing of your sources.  That's the bad news.

The good news is that you will not have to do it, because MPW 3.0 will
ship with the appropriate Canon files that will do all of the
conversions for you!  These files already exist and have been put to a
good test: converting the MPW Shell sources themselves.  Consequently,
the new versions of the Shell are built post-Canonized, and all is well.

So the change will not be a big deal.  It will cause a bit of minor
confusion between people working across MPW 2.0 and MPW 3.0, but for the
average project, a simple bringing forward of the sources will suffice
and the Canon stuff effectively discarded.
