Re: st: Is it possible to use --rename-- with the renumber option to rename variables in reverse order?

[Aaron Kirkman <ak1795mailserv@gmail.com>]

Is there a simpler way to do this in a loop? (I realise this solution
is fairly simple, but I want to make sure I didn't miss something).

****
clear
input v2 v3 v4 v5 v6 v7 v8 v9 v10 v11
309 418 333 153 259 172 359 319 440 317
end

foreach v of varlist v2-v11 {
	local year = 2011 - real(subinstr("`v'", "v", "", .))
	rename `v' v`year'
}
****
