You can use the undocumentend command ds, like in the example below.
For more on -ds- see: -help ds-. (undocumented means that it is not
documented in the paper documentation but there is an electronic help
file, see: -help undocumented-.)

*--------- begin example ---------
sysuse auto, clear
ds , has(type numeric)
order `r(varlist)'
*--------- end example ------------
(For more on how to use examples I sent to the Statalist, see
http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html )

Hope this helps,
Maarten
