Subject:      Proportion of Sample -Reply

Heres a simple solution :
 
proc freq;
tables dummy;
run;
 
Results will look something like this :
 
dummy    frequency  percent   cumul. freq   cum. percent
0                   20             20              20               20
 
1                   80             80            100             100
 
In this example the ratio of 1's to total observations is 80%.

I want to know the proportion of a dummy variable (only having 0 and 1
values) in my data set. That is, the ration of event of interest
(numbers of observations with 1/numbers of total observations) over the
whole sample. I think my method is very tedious. Is there anyone can
contribute a simple way to do that?
 
Thanks in advance.
