My guess is that you're using an older version of VFP, and it's creating a filtered view rather than a real cursor. If current, add the NOFILTER clause to the first query; if early version, add a "WHERE .t." so that it is not fully Rushmore optimizable as a single query from a table, so you get the filter.

Yep - this is the exact behavior described above.

>SELECT dxand.*,cname FROM dxand,demas WHERE dxand.cnoee=demas.cnoee INTO CURSOR ABC
>SELECT cnoee,cname FROM ABC INTO CURSOR BCD

Two tables, so the query can't be satisfied from a filtered view of a single table
