The existence of a path does not mean that a detail exists.  That the
status of the DBFIND call was zero means that the chain head exists.
You can either accept that the DBGET returns EOC (end of chain (or BOC
if a backward read)), or you can test the chain count of the DBFIND to
see if any entries exist in the chain after a successful DBFIND.  If the
chain count is zero, then a DBGET isn't needed.

Subject: [HP3000-L] image conundrum

We have just located a potential problem and would appreciate some
answers
from the image gurus.

Given an automatic master dataset, and two detail datasets.  Both
details
are linked to the automatic master by the very first field in the
dataset.  Given key XXXXX, and a record existing in dataset #1,
performing
a DBFIND on dataset #2 yields a hit (DBFIND DB-STATUS = 0).  But of
course, the DBGET yields nothing.  Does anyone have experience with this
and/or knows the reasons for it?  Is this normal?

We can repeat this problem with multiple databases and datasets.

Thanks in advance for your assistance!
