st: How to create a rank?

["Song" <raravise@gmail.com>]

Dear Statalisters,

I am trying to create 'rank' based on total revenues. I used the following 
command:

sort revenue
egen rank=group(revenue)

The result is that the smallest revenue is 1 and the highest revenue is 100, 
for example. How can I reverse the rank? I want the highest revenue to be 
number '1'.

Thank you,
Reo.
