I fail to see how this question follows from my post, but

1. The official Stata command -cusum- is absolutely nothing to do with
-cusum6- (SSC).

2. As -cusum6- (SSC) still works, there is no obvious need for it to
be replaced with anything.

If that doesn't answer your question, please state what you want to do
and someone may be able to help.

To say it frankly, it's my first time using stata and I have stata12; therefore it's hard for me to know what has changed and from where. How about the other problems I long for answers?
