IIRC, the active record in cursor2 is not moving during the import. The for condition is applied to each record after it is inserted into c_cursor1. As each record is imported it looks at c_cursor2, and sees that the value matches and leaves the record in c_Cursor1. You'd need a relation between cursor1 and cursor2 for the record pointer in cursor2 to move.

To do it really obviously and cleanly,
select * from cursor2 where fld1="123" into cursor c_cursor3 nofilter
select c_cursor1
append from dbf("c_cursor3")
