Please finally clear up my uncertainty.
I have always been used to (elsewhere) using as few Globals as possible, passing as parameters and local variables being passed from a sub to any lower sub.
I cannot seem to get it clear in B4A. I have searched but am still unclear.
I would expect local variables to be passed to lower subs because I have not left the upper sub until I execute End Sub.
I observe that such local variables show as red and thus undeclared, in sub subs.
Is this a true observation?
Is there an extra overhead in using globals?
