I guess so, Jason...it's not highlighted in the classes that need
converting.

Although (to my utter surprise) TIBOBlobStream is declared and
implemented in IBODataset.pas, it hasn't been picked up in either of
the generated T2H Winhelps..meaning it's neither published or protected.

Is it a very recent addition that didn't make it into the release
notes yet? I guess we need it to be published and make a demo for it...
