Many thanks Mike, I'll get back to you as soon as I can.

Thanks. A worrying result from my point of view as it looks like some of the entries just haven't gone in.  We will need to hold back 6.18 from general release until we can find out why this has happend. If you could set back the Dict Seq indicator in the Setting table to 00000015 and run the Dictionary Upgrade again I am hoping this will fix it. .

Mik, I've reset the SETTINGS Deq Seq indicator to 00000015 and am running dictionary upgrades 00000016 onwards. This may not finish by the time I go home so I'll report back with a new output from the ORGANISM report ran earlier.

I believe this is something to do with the order in which the Organism table is processed. Although the order is correct in the table (ie the parents come before their children) it looks like this order is not always adhered to when the dictionary upgrade runs, which means that some records don't go in because their parents are not yet there. Running a second time finds the parent, so a few more go in.  To eliminate this possibility, I have split the table into the 10 levels so that the children can't go in first. There is a new dictionary upgrade at www.Recorder6.info/0000001Bto1N.zip  which implements this. It is designed to run on a Dictionary already upgraded to 0000001A.  I would be most grateful if you would try this for me. You should end up with 108,222 entries in the Organism table.  Don't worry about the report I sent you. It has done its job and can be deleted.
