Hello Ada,
Check the code below. It works fine with the auto dataset.
In your case you will have the change the local command line to
local new_var=lower("`var'")
use auto, clear
foreach var of varlist _all {
local new_var=upper("`var'")
rename `var' `new_var'
}
All the very best,
JP

Subject: Re: st: rename variables UPPERCASE to lowercase
Hi all,
Thanks for all the suggestions. May be becoz I'm crap - I tried both Nick
Winter's and Nick Cox's version and neither works.
When I used these commands:
foreach var varlist QUOTA-UALDWK2 {
rename `var' `=lower("`var'")'
}
Stata returns says "Invalid Syntax" r(198). I tried several versions of it
and
none of it work.
I think I'll stick to (and try to memorise) the "simpler" _renvars_!
