Re: st: -save- a varlist

[Jeph Herrin <stata@spandrel.net>]

Agree - but I was referring specifically to Austin's suggestion of using 
-outsheet- twice, then matching the labels back up to the values. I 
don't think that approach is very easy to implement.
As I stated right off, using -label save- is the most useful suggestion, 
and does make the problem nearly trivial.
