PBDTOpenInform performs the same function as PBDTGetPath, but it

also reports whether the desktop database was empty when it was opened.

If the desktop database was just created in response to PBDTOpenInform

(and is therefore empty), PBDTOpenInform sets the low bit in the ioTagInfo

field to 0. If the desktop database had been created before you called

field to 1.
