Sergey, to make it more meaningful perhaps I would do this....
select detail,noun,sum(price),sum(quantity) from s:bsyear01 group by detail;
into cursor curs_abc
INDEX On noun TO e:f
copy to curs_xyz
brow
I see what you mean that the noun would be meaningless because only 1 record(noun) would show up for all records matching a certain detail.

Select detail, noun, sum(price), sum(quantity) ;

There's nothing in the query that tells VFP from which record to take value for 'noun' column. The query is ambiguous. It's not documented but known that VFP will return value for the columns not icluded in GROUP BY clause from the last physical record in the group. It may or may not be what you want or expect. Even more, the result of the query depends on the physical order of data in the table. If you rearange physical order of data in the table the result returned by this query will also changed.
