*--------------- begin example -------------------
sysuse auto, clear
label define tobedropped 1 "foo" 2 "bar"
label dir
local labs `"`r(names)'"'
foreach var of varlist _all {
local lab ""
local lab : value label `var'
if "`lab'" != "" {
local labs : list labs - lab
}
}
if "`labs'" != "" {
label drop `labs'
}
label dir
