  24  * The contents of a pidl should never used from a application
  25  * directly.
  26  *
  27  * Undocumented:
  28  * MS says: the abID of SHITEMID should be treated as binary data and not
  29  * be interpreted by applications. Applies to everyone but MS itself.
  30  * Word95 interprets the contents of abID (Filesize/Date) so we have to go
  31  * for binary compatibility here.
