There is one thing I would like to point out in José Maria's code.

Note that you cannot label system missing values (ie. .). Labels may
only be associated with extended missing values (i.e. .a, .b, ...,
.z). Thus, you should code

label define labelname 0 "male" 1 "female" .a "missing"

rather than

label define labelname 0 "male" 1 "female" . "missing"

if you want your missing values to be labeled.

Thank you very much.
Your observation/correction reinforces in the thread "What to Tell others to learn Stata in a short time period" the Statalist as an important source of learning.
