For each type of HL7 message you want to send out using the From Database Iguana component, you need to define a unique message definition inside your Chameleon VMD file.

In this example, you will be a generating a simple Register Patient (ADT^A04) message containing an MSH segment followed by a single PID segment.

To create a new PatientRegister message:

• Open Chameleon. The Start Page window appears.

Start Page Window

• Under New, click Empty Project. The Chameleon interface appears, displaying the Message Browser.

• In the Toolbar, click the Message icon. A message definition named Message1 appears in the Workspace.
• Right-click Message1, and select Rename Message.
• Rename this message PatientRegister.

Now that you have a message definition, the next step is to import the segments that it will contain.
