{title:Description}

{pstd}
{opt sysuse} {it:filename} loads the specified Stata-format dataset that was
shipped with Stata or that is stored along the {helpb adopath}.  If
{it:filename} is specified without a suffix, {opt .dta} is assumed.

{pstd}
{opt sysuse dir} lists the names of the datasets shipped with Stata plus
any other datasets stored along the {cmd:adopath}.


{title:Options}

{phang}
{opt clear} specifies that it is okay to replace the data in memory, even
    though the current data have not been saved to disk.

{phang}
{opt all} specifies that all datasets be listed, even those that include
    an underscore ({opt _}) in their name.  By default, such datasets
    are not listed.


{title:Examples}

{pstd}
If you simply type {cmd:use lifeexp}, you would see

	{cmd:. use lifeexp}
	{err:file lifeexp.dta not found}
	{search r(601):r(601);}

{pstd}
Type {opt sysuse}, however, and the dataset is loaded:

	{cmd:. sysuse lifeexp}
	(Life expectancy, 1998)
