'''Q:''' ''I have FileMakerPro 6 and 7 on the same machine. How can I be sure I open the right one ?''

'''A:''' With {{{fm = app('FileMaker Pro')}}} or {{{fm = app('FileMaker Pro.app')}}}, you'll never know. Use {{{fm6 = app(id='com.filemaker.filemakerpro')}}} for FileMakerPro 6 and {{{fm7 = app(id='com.filemaker.pro7')}}} for FileMakerPro 7.
