STATEMENT:  Sub
Sub
 
The Sub statement creates a subroutine, assigns a name, and allows you to list arguments which are to be passed into the subroutine.
 
The major difference between a subroutine and a function, is that a subroutine cannot return any value back to where it was called from.
 
As an option, subroutines can be declared Private or Public. You can call other subroutines and functions from within a subroutine (nesting). You must end every subroutine with End Sub or you will get an error message. One option for leaving a subroutine is to use Exit statements.
 
Code:
<% Sub aardvark %>
   <% Rem you can place all of the code you desire inside a subroutine %>
<% End Sub %>
 
Code:
<% Private Sub aardvark %>
   <% Rem you can place all of the code you desire inside a subroutine %>
<% End Sub %>
 
You can list more than one argument in the subroutine.
 
Code:
<%
Sub aardvark(myvar1, myvar2, mynumber, myarray)
   Rem you can place all of the code you desire inside a subroutine
End Sub
%>
