Have you ever tried putting a variable in a data section? Something along these lines:

.someLabel
Data test,0,0,0,0

I was curious to see if you could do something like. Apparently not, but it does not cause the program to crash immediately. Instead it prompts the user to open a .bb file, and then crashes afterwards.

Has anyone else noticed this? Why does this happen?

Data fields are stored in the executable. That is why they should be constant. Basically, you can't use variables as a Data field. You could however, use a String:

Data "test", 0, 0, 1, 0

For i = 1 To 5
   Read d$
   Select d$
   Case "test"
       val = test
   Default
       val = d$
   End Select
   Print "value:" + d$
Next

That answers part of the question, but why would it want to open a .bb file?

This sort of thing has been known in various forms for years. If a Data statement is malformed then a file requester may pop up. Nobody knows why.

Thanks. I'm relatively new to programming, so I hadn't heard about that before.

Yarp. Old bug.
