Thank you for the additional assistance, Bill. It is sure to be useful for the future. As for the problem in question, since I cannot reproduce it using v6.01 I guess I'll get back to the main task of programming, and hope that the changed code does not evoke this failure when I load it in a v5.04 environment.
