I have a huge list of variables in the form of

I am intend to only copy var1, var 2.. var N to another stata file.
How can I realize this?

There are a few different ways, depending upon how your variables are named.
If they're named with a numeric suffix, then -keep var*- (or -drop par*-),
and away you go.
On the other hand, if you're interested in keeping alternate variables, then
look into handling it with the aid of macros and loops (illustrated below).
