-codebook- does not save that information; it appears, in fact, to only save info about problem variables

however, -unique- does; this program is available via -ssc-

Dear all,

Does anyone know why I get nothing with -return list- after
-codebook-? I did check the ado file of -codebook- and it is an rclass
command. It also seems a series of r() are well defined in the
program.

My purpose is to get the number of unique values of a variable stored
in a scalar or macro. Any suggestion of achieving this, maybe in other
ways, will be appreciated. Thanks a lot.

Best,
Luhang
