Jon described how to set the default directory, but there is often a lot
of confusion between the default directory and the directory displayed
by the StandardFile package.  If you want to set the StandardFile
package's displayed directory, you do so by setting the low memory
globals:
SFSaveDisk=$214;
CurDirStore=$398;

Set SFSaveDisk to -vRefNum and CurDirStore to the dirID of the folder.
To get the dirID of the folder, use PBGetCatInfo (be careful, there are
two dirID's in the paramblock, ioDrDirID&ioDrParID, one is right, and
one is wrong :-)

Have fun,
   Peter.
