∟Sub (Subroutine) Procedure Example
This section provides a tutorial example on how to use a subroutine procedure. A 'Call' statement should be used to invoke a subroutine procedure.
Here is a short example of subroutine procedure, function_sub.html:
<html> <body> <!-- function_sub.html - Copyright (c) 2015, HerongYang.com, All Rights Reserved. --> <pre> <script language="vbscript"> Call Hello("Tom") Hello "Herong" Sub Hello(sName) document.writeln("") document.writeln("Hello " & sName) End Sub </script> </pre> </body> </html>
Here is the output:
Hello Tom Hello Herong
Notice the two different ways of calling a subroutine.
