Wow, very very cool. Thanks you for taking
the time to pass this along. Being able to keep the stacks inside the OSX application bundle will/would be fabulous.

We meaning many of us here... do this all the time.
I love keeping stacks inside the OSX application bundle,
  you can develop them from inside there and ship as as single binary..

There are two common approaches These scripts may help

on loadFromDisk
     -- Setting the default folder.
     set itemdel to "/"
     set the defaultfolder to item 1 to -2 of the effective filename of
this stack

     -- Check for application
     if there is not a file "MyNoteBook.rev" then
         if checkNet() then
             checkNetworkAndDownload #If you don't have it locally then
get it from the web server
             exit loadFromDisk
         else
             answer error "Please connect to the internet to install
this application"
             exit loadFromDisk
         end if
     end if

     go stack url "binfile:MyNoteBook.rev"
     hide  stack "MySplashEngine.rev"
end loadFromDisk

---------

on preopenstack
   go stack url (getPath("MyNoteBook.rev")
end preopenstack

function getPath tStack
     set the itemdel to "/"
     put the effective filename of this stack into tPath
     put tStack into item -1 of tPath
     return tPath
end getPath

By separating the function you have the interesting option of offering
the user the option to open any number stacks you might bundle into the
same folder:

On the splash screen you can have a pull down menu like this

on mousedown
    set the defaultfolder to item 1 to -2 of the effective filename of
this stack
    put the files into tFiles
    filter tFiles with ("*.livecode")
    put tFiles into me
end mousedown

on menuPick pStack
     go stack url (getPath(pStack))
     hide this stack # hide the splash screen now...
end menupick

Now you can put what ever stacks you like into that folder.

Don't forget to include quit handlers in all the stacks so that you
don't leave a hung process Hidden splash screen still running.

HTH

aloha





Mark assuming that you will always put the data stacks in the same
folder as the splash-engine stack
