Hello Alan

Here is the code I use frequently:
USE myDBF
AFIELDS(laDummy,'myDBF')
CREATE CURSOR myNewDBF FROM ARRAY laDummy
USE in myDBF


>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.
