st: randomly assign btw datasets

["Aaron Li" <ylacademics@hotmail.com>]

Hi,

I want to generate a random sample of combinations between a group of firms 
(#=100,000) and a list of industry SICs (#=50) (in two datasets). I could 
use cross to generate all possible combinations and then random sample. 
Because the resulting dataset would be huge, I decide to do it another way: 
random sample the # of firms (say, 30,000), and then randomly assign one SIC 
to each sampled firm. How can I do it? Thanks for your help.
