V4RB RecID and String Method problems

Thanks Ruslan,

Actually, in my implementation I do not delete any records (these are sales transactions that would never change once they are inducted into the Valentina DB) but I do understand the danger.

I have been using RecID as the unique key to each record.  Being able to determine the maximum and minimum aggregate functions on RecID would be most useful.  Strangely, Count(RecID) is working for me so I am guessing some of the functions are working.

regards
Mike
