Mark,
    I haven't seen any code to compute a full HFS pathname to a file from it's
    filename and WDRefNum (Does anyone have code?), but if you use GetVol
    and SetVol, you shouldn't have any problems.
	
    I hope this code segment helps.
	
	....
	GetVol(NULL,&currVol); /* Get default volume now for restoration after
				  fopen() call */
	SetVol(NULL,reply.vRefNum); /* Set default volume to volume abtained
					from SF{Get,Put}File call */
	PtoCstr(reply.fName);	/* Convert fName for fopen() call */
	fp = fopen(reply.fName,"r"); /* open */
	CtoPstr(reply.fName);		/* balance PtoCstr() */
	SetVol(NULL,currVol);		/* restore */
	....
