Re: how to set path?

["web" <jiali3(at)21cn.com>]

Thank you. I set path like you. I donot think it's a good method. When I
change directory, I have to change all, especially when I generate a .sav
file and run on another computer.

Sometimes, When I donot set full path, it can work. But sometimes it cannot.
Why?
