ByVal :- Byval is address the actual value of the variable.
Ex:- Function abc(Byval var)
var=var+1
End Function
Dim x:x=2
abc x
Msgbox x
In Above example 2 is the Actual value so it address the
actual value,the Result is 2.
ByRef:- ByRef is address the Location of the Stored variable.
Function abc(ByRef var)
var=var+1
End Function
Dim x:x=2
abc x
Msgbox x
In above example it 2 actual value but in byref it refers
the location of the stored variable the result is 3.
