-- Is there any function hidden in IM somplace that returns a full
-- path name given an SFReply?

There is no toolbox routine to return a full path name, but doing it 
yourself is fairly easy. 
Here is a C routine to do it (gleaned from some DTS sample code)...

/*
**pathName (dirID,vRefNum,s)
**returns a string containing the full pathname to the current file or 
directory
**this code is snached from the DTS sample code StdFile.c (but slightly 
modified).
**Added support for both files and directories.  Don't give a flying *#@! 
if it 
**breaks under A/UX, thank you very much....
*/
char *pathName(dirID,vRefNum,s)
long dirID;
short vRefNum;
char *s;
{
  OSErr err;            /* error container                    */
  CInfoPBRec block;     /* infoBlock to be used CatInfo calls */
  Str255 directoryName; /* a place to stuff my directory name */

  *s = 0;
  block.dirInfo.ioNamePtr = &directoryName;

  block.dirInfo.ioDrParID = dirID;

  do {
    block.dirInfo.ioFDirIndex = -1; /* Specify vRefNum and DirID for call */
    block.dirInfo.ioVRefNum = vRefNum; /* set the ParamBlock's vRefNum       */
    block.dirInfo.ioDrDirID = block.dirInfo.ioDrParID; /* set the ParamBlock's
DirID         */

    err = PBGetCatInfo (&block,false);/* get information on catalogue       */
    if (err) break;/* get me outta here......            */

    pStrcat (&directoryName,"\p:");/* add a colon to the begining...     */
    pStrcat (&directoryName,s);/* prepose newly found directory name */
    pStrcpy (s,&directoryName);/* swap the two  */

    } while (block.dirInfo.ioDrDirID != fsRtDirID);/* loop till we hit the 
root */

    return (s);/* cough up the result  */
}

Hope that was helpfull.
