On the right-hand side of the page that appears when you choose Help > Max Help, you'll see three "Messages to...." links - one for Max, one for MSP, and one for Jitter. Those three links constitute a complete listing of all possible and supported messages of the type you describe.

Hi Greg, thanks for the quick reply!

I have found these vignettes to be incomplete, actually. I am trying to find documentation on what are the executable messages that follow the operating system in the max system message. This is what it says in the documentation verbatim:

system The word system, followed by the name of an Operating System (windows or macintosh) and a message, will execute the message if Max is running on the named OS.

Nothing in what the messages are exactly. Further evidence that this list is incomplete (hence my cry for help here), is that the "launchbrowser" documentation would lead you to believe that launching a browser is its only function, however a carefully formatted "mailto:" message will in fact launch the default mail application. I have been told "launchbrowser" is even capable of launching any app with the correct message.

Very frustrating to have incomplete/misleading documentation. Or am I just missing something?

The "system" part does not work how you expect. It will run any of the messages to max providing you are using the specified system: windows or macintosh. The example below will only open on a pc, not on a mac.

However I do think a bit more information in the docs on launchbrowser in particular wouldn't be a bad idea.
