Bug? accessing LOCAL var in shared scope

[lenborje]

Thank you for the explanation.

I must add that what confused me in Han's hint was that I did not understand what CAS had to do with it.

I understand now that colDim is a CAS function. This was not immediately apparent to me.

Are all functions with mixed case names CAS functions, or is there some other way to distinguish between CAS and "normal" functions?
