After altering the variable order, such as with a -merge-, is there an easy
way to re-order the variables in their original order?  I'm doing it now in
a round-about way (below).  There must be a more direct way.  I've looked
through Stata's extended functions and -creturn list-, and searched with the
keyword _all, but came up empty-handed.  There's probably something that
I've stared directly at, but didn't see.

program define allem, rclass
   syntax varlist
   return local all `varlist'
end
allem _all
[commands that change variables' order]
order `r(all)'
