What I've done to deal with THINK C projects vs built applications is this:
	GetAppParms(apName,&apRefNum,&signature);
	if (signature = GetResource(ApplCreator,0))
	{	/* this way we can use Lightspeed C */
		apRefNum = fb.ioRefNum = HomeResFile(signature);
		ReleaseResource(signature);
	}
	else
		fb.ioRefNum = apRefNum;

This way, if we want to add data to either fork of the current app 
if it's built or to the rsrc file if it's running with a project, 
we're covered.  Here, I assume that there is a signature resource defined
by ApplCreator.  If we're running from the project, it's in the .rsrc file,
and if we're running in a built app, it's in the app.  If it isn't there,
we have the apRefNum anyway, so we're covered (in the case of running from
the project, we'll write into the project file, not such a good idea, but
if you do this early on in the app, you ought to have enough memory, and 
as long as you remember to put the signature resource in there, you'll be
ok).  Yes, I know this is not the way to add preferences.  This is how
one might personalize an application.  BTW, fb is a param block later
passed to PBGetFCBInfo.
