New If I'm not mistaken...
Having the same option in multiple case statements is legal in VB but it only peforms the first case that is matched.

New poor substitute for Boolean expressions
Having the same option in multiple case statements is legal in VB but it only peforms the first case that is matched.

You are right. Bad example on my part.

But, if you want potentially multiple blocks to execute, then you might as well use IF blocks. I tend to shift to IF blocks for all but the simplest of case statements anyhow. They scale better in complexity.

And, I don't like BREAK statements. Too easy to forget, and they are a dumb substitute for Boolean expressions IMO. Too Goto-like.
