Request for sample Automation program

I've been trying to implement a simple Automation server that receives a string of text and sends back a report, and I'm having trouble wading through the User Guide/Reference Manual.  It isn't obvious to me what the code for such a server would look like.  What I really need is a soup-to-nuts example of LispWorks OLE/Automation programming code that can compile into a working DLL.  That would make it easier for me to implement what I want to do--a simple automation server applications that receives a string of text and outputs a string of text.  For example, if you have a method that sends the string "hello" to it, the server might respond with "hello world".  Thanks in advance for any helpful replies.
