Preprocessor Message Variables

[Yorkie]

I'm looking at the preprocessor at the moment and wonder what variables/functions are available to identifier the source of the message, message type, details of the channel it's targeted at etc. etc.

How would I for instance only target a JavaScript mod on messages for channel 1, but not 2 and 3? or all HL7 messages, but not XML?
