OK, so we're writing a device driver for the MAC. We use MPW 3.0
Pascal.  This is our first driver attempt.  We've heard miscellaneous
rumors about the dreaded 32K boundary.  For the first six months,
things were great, we coded away and the driver was running great.

But then ...

We hit the limit.  No bells rang, no whistles blew, the MAC police
didn't come and arrest us.  The only sign that something was amiss was
a link message:

### Segment: MyDrvr, size = 32924

In ResEdit I verified that the DRVR resource was indeed that length,
everything looked okay.  Being a rebel and a daredevil, I went ahead
and ran the thing.  Everything looks okay.

Question: Is everything really okay?  Was something truncated to 32K?
And if there is a problem, what can we do about it?

Thanks in advance,

Jay
