Thank you for your reply, John. I'am afraid, it might not solve my problem. I guess I did not state the problem clear. The problem is not just related to RELEASE ALL. I tried to remove RELEASE ALL, then it reported same error at next statement CLEAR ALL. If I do not run cleaning up, I get other error for not cleaning up.
