how to add*observations at the end of the observations for existing variables?

[Fred Lee]

When name and year exist, I cannot use the command below because it says variables already exist. how to insert some observations quickly?

input expName year
刘洋   2015
彭蓉   2015
方静   2016
杜海燕   2015
石书田   2015
邵宗义   2015
金源祎   2016
陈伯爽   2015
end

I know a stupid way is
set obs ...
replace ...in...

But when I have a lot of observations to add, I guess there should be a better and more direct way.
Thanks!

Probably the fastest way is to -save- your original dataset, -insert- your new data, and then -append-. Illustrated below (begin at the "Begin here" comment).
