I doubt the Transcript code would be much simpler than the C# <g>:

System.Guid desiredGuid = System.Guid.NewGuid();

but I second Dar's concern over the "bona-fide" qualifier. Microsoft's
implementation has been criticized as being unsecure - the MAC id can
still be identified from the guid, and therefore documents can be
trace to their owners - that's how the writer of the Melissa virus was
found. The "standard" way of generating a guid involves the MAC id and
a time string - are you looking for something more secure than that?
