Launching rev app from file on Mac

[Thomas Speitel]

On a System 10 Mac I wish to launch a rev app by double-clicking on a  
text file created by the app. I have the filetype with the registered  
creator name. When the app opens I would like the text file to appear  
in the app's field. Help appreciated.
