	If I were you, I would NOT rely on the PMSP (poor man search path) as
I would assume that it will disappear in the future (it is SUCH A HACK!).  
Instead why not use SysEnvirons to get the blessed Folder's RefNum (from 
field sysVRefNum) and then do a SetVol to get to that volume (don't forget
to save the previous volume and restore it when done!)
	This will make you code a LOT MORE compatible in the future should 
things like the PMSP disappear - it also makes it more intuitive as to what you
are ACTUALLY doing!
