Betreff: Re: st: Comparing Variable Name Labels Between Datasets

Beth, how about something like this:

*save variable labels as local macros
sysuse auto.dta
foreach var of varlist _all {
local `var'd1: variable label `var'
}

clear
sysuse auto.dta
*create erros in variable lables and save as local macros in second dataset
label var make "price"
label var price "Make"
foreach var of varlist _all {
local `var'd2: variable label `var'
}

*compare and list differences

foreach var of varlist _all {
capture assert  "``var'd1'"=="``var'd2'"
if _rc~=0 {
	if "``var'd1'"~="``var'd2'" {
		di "Error in `var'"
		di "First label: ``var'd1'"	
		di "Second label: ``var'd2'"
		}
	}
}


Error in make
First label: Make and Model
Second label: price
Error in price
First label: Price
Second label: Make

hope this helps, Tim
