Functions
Functions are defined similar to Subroutines:
<%
Function Add (A, B)
Add = A + B
End Function

%>
As seen above, the function Add adds two numbers and returns their result.
You can call this function as:
<%
Response.Write Add (2, 3)
%>
which will produce the sum as the output. More complex processing may be
done inside function bodies.
<%
Function Calculate (A, B, Op)
Select Case Op
Case “+”
Calculate = A + B
Case “-”
Calculate = A - B
Case “*”
Calculate = A * B
Case “/”
Calculate = A / B
End Select
End Function
%>
<%
Response.Write Calculate(2, 3, “+”)
Response.Write Calculate(2, 3, “-”)
