What is the scope of a variable ?
The scope of a variable defines whether a variable will be accessible in the whole function or will be accessed only to its local instance.I have defined earlier in the tutorials that they can also be deemed as a local variables or can be deemed as a global variables.
For ex.
< script >
Dim name
Sub cmdclickme_OnClick
Dim age
End Sub
< / script >
It is clear from the above example about the scope of the variable that the variable name will be available to the whole script as it is declared outside sub procedure so enhance his behaviour to the global as compared to the variable name age which is defined inside the sub procedure hence making his behaviour local and will be only accessed in this sub procedure only.
