Searched archives, read the latest manual, including chapter 11 on btrees,
but I'm too thick to figure this out:

In an image base I have
FLEET-MASTER indexed on its key item FLEET.
SCHEDULE is detail to FLEET-MASTER. (searchitem is FLEET; no choice,
right?).

In a screen pgm I do
DBFIND mode 1 set FLEET-MASTER search FLEET arg @.
Then the user chooses fwd/bwd via F1/F2, invoking DBGET mode 5/6 vs
FLEET-MASTER, getting each in ascii sequence.

Works great.  But I want to display the detail chain too...
DBFIND mode 1 set SCHEDULE search FLEET arg {the specific fleet}
DBGET mode 5 until end of chain, still great.

How do I get back on the b-tree chain for the next F1/F2?
