st: using e() to retrieve result

[Sean Shu <sshu@hkpr.on.ca>]

Hi, all

I have caculated CI for my survey data via command: "svymean dummy1 
dummy2 dummy3". I like to re-use CI and std. error result in my program. 
According STATA user guide, e()is the right command to use. But I can 
not figure out what syntax should be put inside the ()- e(ci)or e(err) 
would not work. Any help?

Thanks!

Sean
