st: Re: sampling problem

I'm not sure what else you may want to do between calls to samplepps, but it 
seems like you may want to use a forvalues or foreach loop.  If you just want to 
create 5 new variables resulting from repeated calls to samplepps, then 
something like this may work:

local vals "100 240 300 350 412"
foreach val of local vals {
  samplepps sample`val', ncases(`val')
}

of course, you would need to add in any other options you want to the samplepps 
command and you may want to name the new variables differently, which you could 
do by creating a counter in the loop.

By the way, you shouldn't include an old message in your posting -- please 
follow the faq.
