From: Ellen K. 

Some of my cousins were in town yesterday and we had dinner.   On
learning I program in VB, one of them asked "16-bit or 32-bit"?   I
almost fell off my chair.    She apologized by saying the way I'd been
describing Kaiser, she wouldn't have been surprised to learn I was doing
16-bit there.

I didn't realize integer division was also affected in the way you
describe.   What about Mod?

The biggest thing that surprised me in VB after learning C/C++ was
arguments being passed by reference as the default.  VB7 (the .Net version)
has changed that, now ByVal is the default.
