Dear Stata users,

Command -labellacking- was written by Nick Cox and Robert Picard. (Distribution-Date: 20130702). I often used it to check variables that with values lacking value labels. I find the command can't run sucessfully under Stata 16. Could anyone tell me how to modify it? Example as belows, all variables in my dataset have values labels, however labellacking list all of them (and that is a wrong hint).
