What about this:

*-------------- begin example ------------------
drop _all
set obs 20
gen obs = _n
gen unif = uniform()
sort unif
keep in 1/10
drop unif
list
*-------------- 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
