st: Drop unused value labels

Dear All,

I am wondering whether it is possible to remove all unused value labels (i.e. all value labels that are not mapped to a variable) from a dataset without having to specify each label name. Would anyone know whether there is a way to do that in official stata, or whether a user-written program exists?

Thanks in advance for your help, regards,

Elmar
