I want to randomly assign, with replacement, 200 industry SIC codes

--------------------------------------

I don't know what SIC codes are. In the solution below I assume that
they somehow can be numbered from 1 to 200.

The first three lines generate a small artificial dataset, just for the
demonstration. On the functions used, see:
   . help uniform()
   . help int()

clear
set obs 100
gen firm=_n
gen sic=int(200*uniform())+1

Hope this helps
Svend
