st: To expand the value of a constant variable across the panel

Dear statalisters,
I have longitudinal data where patients have information on several timepoints.
Some values from constant variables are missing. How should I fill in
these observations across the panel (pte id)?
Example:
pid visit# gender
1 1 1
1 2 .
1 3 .
1 4 1
2 1 .
2 2 .
2 3 0
2 4 .
etc..................
I did tried the ssc program "enlarge" but reported error when values
existed more than once (as in pte 1).
I would appreciate any help,
Eduardo
