- It sounds like you ran across a particularly nasty bug in the Pascal compiler.
- From your description, it sounds like a problem that occurs when compiling
- with the -MC68881 option. When you do this, Pascal dereferences your object
- handle into a scratch register (such as A0), and then calls other procedures,
- forgetting that the scratch register could get wiped out by those subroutines.
- Using SELF explicitly is the workaround for the problem until MPW 3.1 is
- available.

- P.S. Andy would have answered this, but he was particularly miffed that you
- spelled his last name "Shevanow" rather than the more correct "Shebanow" (or
- the even more correct "Klebanow"). Now we've got to talk him off the roof.
- This wasn't so bad in our last building, but we've recently moved into an 8
- story affair, and things haven't been too stable after the earthquake...
