Labels

Variable and value labels are defined using the label command.

label variable foo "yes or no?"
label define yesno 1 "Yes" 0 "No"
label values foo yesno

See here for more options.

Numeric values can be quickly prepended to value labels using the numlabel command.

numlabel foo, add mask("#. ")

display _N    // number of cases
display c(k)  // number of variables
