I think you nailed it Mike. I simplified my post a bit. I'm actually
testing a parameter to a function not a variable and the call to the
function does not pass the parameter. In other words:
put myFunction(p1) into whatever
function myFunction p1,p2

end myFunction
This
on mouseUp pMouseBtnNo
put empty into tVar
put tvar is not zero
end mouseUp
results in true. Not sure what is going on there.
