st: basic commands question

[Yihong Ni <yihongni@fas.harvard.edu>]

I have a questions about using stata8:
Is there any way to save the results of tabulate command in another .dta
file?

Or..
why does the following code not work?

. by (var1 var2): egen freq=count(var3)

I want to count the number of occurences  (var3) for each year for each
country.  how do i save this reorganized result in a .dta file?

thanks for any help!

Nancy
