The August 97 (Sixth Edition) of the HP TurboIMAGE/XL
DBMS Reference Manual also contains a little info on
Jumbos;  and DBINFO Modes 206 and 207 for retrieving
the number and size of Jumbo Chunks.

I've mentioned it before and will say it again:  Every site
running a recent release of IMAGE should have their very
own copy of the above Sixth Edition;  it has a lot of good
stuff about new IMAGE features that have been implemented
in the last few years.  IMHO HP did a good job on this manual.
