Variable scope and lifetime

[newuser123]

I seem to be confused by these two concepts.

Dim a As Integer
 
Sub Firstproc
 
a = 10
 
Call Secondproc
 
End Sub
 
Sub SecondProc
 
Dim b as Integer
 
b = a
 
End Sub

As a is declared at the module level, Secondproc can "read" it.

This is an example of scope but what is lifetime?

Thanks
