please help me understand the use again statement.

use out
select * from out into cursor temp where out_pk = 1001

select temp
browse
* temp has one record

USE DBF('temp') AGAIN IN 0 ALIAS temp2
select temp2
browse
* temp2 has all the records in out

replace out_pk with 1002

*not only does it change the record in temp2 but it changes the record in out

what if you don't want the changes to reflect in the out table, you only want to modify the cursor. do you have to use the create cursor statement.
