To create a sorting engine VMD file:

• Open Chameleon, create a new empty project, and click the Message icon on the toolbar twice. This creates two new messages in your Workspace.
• Rename the first message Acme and the second message Magic.
• In the Workspace, expand the Acme message definition. Double-click Identity to open the Identity window, and set the message identity to match messages whose Message Code is SIU. (This is the first subfield of field MSH.9.)

• Expand the Magic message definition, open its Identity window, and set its message identity to match messages whose a Message Code is ORM.
• Click Workspace > Import Segments From Library. The Import Segments From Library window appears.
• Select the HL7 2.6 library, and click Next.

Importing the MSH Segment

• Check the MSH segment and then click Next > Finish.
• Add the MSH segment to the segment grammars of both messages.
• Save the file in the same directory you saved the sample C++ project. Set its file name to sorting_engine.vmd.
