Hey Bill,

Mac:

Here is some appleEvent code you should put in the message path. Since  
you use the splash stack design I would put it in a library stack so  
that it catches the message regardless of which stack is frontmost.  
Note that you may need to check that your application has finished  
loading in the appleEvent. If double-clicking on the file causes the  
OS to launch your application then the appleEvent might be received  
before all of your application stacks have opened.

on appleEvent pClass, pID, pSender
     if pClass is "aevt" and pID is "odoc" then
         request appleEvent data
         put it into theFiles ## files OS is requesting your  
application opens.

         if theFiles is not "not found" then
             if theFiles is not empty then

                 ## DON'T PASS, CRASHES CAN OCCUR (TESTING UNDER 2.8)
             else
                 pass appleEvent
             end if
         else
             pass appleEvent
         end if
     else
         pass appleEvent
     end if
end appleEvent

Windows:

If your application is not running yet then the file paths will be  
passed in the command line arguments - $1, $2, etc. Revolution 2.9  
added $# which tells you how many command line arguments were passed  
to the application so the following code will create a return  
delimited list of argument passed to your application at launch. It is  
up to you to verify the params are paths to one of your files.

repeat with i = 1 to $#
    put value("$" & i) into theValue
    put theValue & cr after theFiles
end repeat

If your application is already running then you need to handle the  
'relaunch' command in the stack you use to create the executable.  
Again, you should check that your application has finished loading  
before doing anything as the relaunch command could be sent before  
your application has completely loaded (you are using splash stack  
technique).

on relaunch
     repeat with theCounter = 1 to the paramcount
         put param(theCounter) & cr after theFiles
     end repeat
end relaunch

Linux:

No idea, sorry.
