{title:Description}

{pstd}
{opt codebook} examines the variable names, labels, and data to produce a
codebook describing the dataset.


{title:Options}

{dlgtab:Options}

{phang}
{opt all}
is equivalent to specifying the {opt header} and {opt notes} options.  It
provides a complete report, which excludes only performing {opt mv}.

{phang}
{opt header}
adds a header to the top of the output, which lists the dataset name,
the date that the dataset was last saved, etc.

{phang}
{opt notes}
lists any notes attached to the variables; see {helpb notes}.

{phang}
{opt mv}
specifies that {opt codebook} search the data to determine the pattern of
missing values.  This is a cpu-intensive task.

{phang}
{opt tabulate(#)}
specifies the number of unique values of the variables to use to determine
whether a variable is categorical or continuous.  Missing values are not
included in this count.  The default is 9; when there are more than 9 unique
values, the variable is classified as continuous.  Extended missing values
will be included in the tabulation.

{phang}
{opt problems}
specifies that a summary report is produced describing potential problems
that have been diagnosed:

{phang2}- variables are labeled with an undefined value label{p_end}
{phang2}- incompletely value-labeled variables{p_end}
{phang2}- variables that are constant, including always missing{p_end}
{phang2}- trailing, trimming, and embedded spaces in string variables{p_end}
{phang2}- noninteger-valued date variables{p_end}

{pmore}
See {help codebook problems} for a discussion of these problems and advice on
overcoming them.

{phang}
{opt detail}
may only be specified with the {opt problems} option.
It specifies that the detailed report on the variables not be suppressed.

{dlgtab:Languages}

{phang}
{cmd:languages}[{cmd:(}{it:namelist}{cmd:)}]
is for use with multilingual datasets; see {helpb label language}.  It
indicates that the codebook pertains to the languages in {it:namelist}
or to all defined languages if no such list is specified as an argument to
{opt languages()}.  The output of {opt codebook} lists the data label and
variable labels in these languages and which value labels are attached to
variables in these languages.

{pmore}
Problems are diagnosed in all these languages, as well.  The problem report
does not provide details in which language problems occur.  We advise you to
rerun {opt codebook} for problematic variables; specify {opt detail} to
produce the problem report again.

{pmore}
If you have a multilingual dataset but do not specify {opt languages()},
all output, including the problem report, is shown in the "active" language.

{phang2}{cmd:. codebook inc*m inc*f, problems}{p_end}

{phang2}{cmd:. codebook _all, problems detail}{p_end}


{pstd}
