          I'm not sure what you mean with package data, depending on
how you built your package, you should be able to access everything
from that pointer, following the slots.
   
       The usual way to get a foreign file format into the newton is
using the LoadDataFile method.

       Something like this: constants.txt contains this:

    DefineGlobalConstant( 'MyDataFile,
                                            
LoadDataFile("maskedalibi.prc",'binary),
                                        );

   
    You add constants.txt to your project, make sure it is above your
main layout or program, and then you can access it from the main layout
using the symbol 'MyDataFile.

    You can also take a look at how MOD files are made here for some
more hints: http://roger.trideja.com/newton/modplayer.html

    I also used this method for writing MP3 files into a soup, here's
some code:
