ASP ByRef lets functions return multiple values at the same time several practices

Let's use an ASP tutorial to illustrate how to back up a number of values when user-defined function calls, first to look at a set of code

<%
Call Getmynumber (AA,BB,CC)
Response.Write AA & "" & BB & "<br/>" & CC
function Getmynumber (ByRef aa,byref bb,byref cc)
Aa=3
Bb=4
CC =10
End Function
%> here is the use of ByRef to see the detailed

         sub Test (ByRef A As Integer, ByVal b As Integer)
 & nbsp;           A = 3
              B = 4
         end Sub
         sub Main ()
              Dim A As Integer
              dim b As Integer
              a = 1
             b = 2
              test A, b
              MsgBox "A=" & A & "b=" & B
          end Sub
          The output a=3;b=2byref effect is the address parameter, which implements global control through the memory addresses of the operation parameters,
