...and it works, when the application is a finished, stand-alone application.

Let me clarify what I'm trying to do with question #2 above...

I'm using LSC to write a program that get some of its startup information from
the data fork of the current resource file.  The information is written there 
by another application.  So, application A writes to B.rsrc, and application B 
is trying to read the data fork of B.rsrc (when in LSC, and B itself, when 
standalone.)  Thus my problem is to keep it consistent whether I'm running an 
LSC project or the standalone application later.

I've tried using CurResFile() to get the ioRefNum of B.rsrc, then passing it
(along with vRefNum and the neccessary stuff) to PBGetFCBInfo(), which comes
back with an OSErr of -38, File not open...

Well, if anybody has any suggestion... I'm game to try anything.
