Dear Experts

I get some data using following commands

SELECT CODE,DESC FROM MASTER;
WHERE LEN(ALLTRIM(STR(CODE)))=6 .AND. DESC LIKE SNAME;
ORDER BY DESC;
INTO cursor TEST15

But in other forms if I use above commands then it show following error message

Cursor name is already in use

How to release cursor name to get rid of above error message in other form?

What should I write on unload event of form to release curosr?

Please help
