I read about scoping in 'Advanced R' and still didn't figure this out.

It's important to distinguish between a variable and the value it is holding.

This allows the caller to omit that argument when calling the subroutine.
For example, if one defines a function as def f(x) : . The function's return type is also a double. Refer to https://en.wikipedia.org/wiki/Parameter_(computer_programming) which can take you over the steps

Within the procedure CountTo, there is no way to reference the global I

Not tried it with combo boxes but this has worked for me with other controls. It would only have been a separating edge if that had not been the case

Function declares a function, Sub declares a subroutine. Only functions may return a value to the caller. Use ByVal or ByRef to explicitly declare your procedure parameters.
The function will stop calling itself once the span distance reaches one.
