Eben,
One of the most important Image lessons I learned (IIRC from Alfredo R?),
and you should now pick up from the answers to your question, is that the
Image Manual is an extremely well written document, and it contains
EVERYTHING you need to know to use the product well. Certainly there are
other very useful books that can teach you many tricks about Image, but all
the base information is in the original manual.
I suggest that you go back to it and become closely familiar with all the
data returned in the status array from every call, because this will enable
you to understand it much better. I hope to be able to hear some "Ah-HA!"
all the way down here.
I have seen code by people who do not know how it works that contains much
wasted effort , such as saving and restoring next record pointers in chained
get code.
Work out how to do a serial read of a master and delete selected records
without doing multiple passes due to migrating secondaries......

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!
