	{cmd:discard}


{title:Description}

{pstd}
{cmd:discard} drops all automatically loaded programs (see
{hi:[U] 17.2 What is an ado-file?}); clears {cmd:e()}, {cmd:r()}, and
{cmd:s()} saved results (see {helpb return}); eliminates information
stored by the most recent estimation command and any other saved estimation
results (see {helpb ereturn}); closes any open graphs and drops all sersets
(see {helpb serset}); clears all class definitions and instances (see
{helpb classutil}); and closes all dialogs and clears their remembered contents
(see {help dialog programming}).

{pstd}
In short, {cmd:discard} causes Stata to forget everything current without
forgetting anything important, such as the data in memory.


{title:Remarks}

{pstd}
Use {cmd:discard} when debugging ado-files.  Making a change to an ado-file
will not cause Stata to update its internal copy of the changed program.
{cmd:discard} clears all automatically loaded programs from memory, forcing
Stata to refresh its internal copies with the versions residing on disk.
