I wish to create a temporary empty cursor structure based on an existing table using SELECT * FROM MyTable INTO CURSOR MyCursor READWRITE WHERE .F.. Is the WHERE expression evaluated for every record? MyTable.dbf is very large (over 2 million records) and I am concerned this may affect performance.

Any help would be appreciated.
