I'm obviously doing something wrong in WordBASIC, but I can't figure out
what. Here's the situation.

I built a WordBASIC dialog box with an OKButton, a CancelButton, and a
ListBox. If I choose the OKButtong, I get the expected results and can
proceed with the next action based on my list selection. However, I run
into problems when I press CancelButton and want to act on it.

The WordBASIC ref manual says that I can use

	On Error Goto 0

to ignore the error generated by CancelButton and use the Err value that is
returned. However, using 'On Error Goto 0' doesn't seem to do anything.
I still get a runtime error and cannot process the error code returned
by Err. I tried 'On Error Resume Next' and that seems to work as
advertised (the cancel generated error is ignored and the next
WordBASIC instruction is processed).

Any hints would be appreciated...todd
