RR estimates using proc Genmod for categorical variables

[ssulli11]

Good afternoon!

I am looking to get RR estimates for my proc genmod regression for categorical variables where there is more than one option.  For instance, I have three age categories and would like to see the estimates of each age category (compared to the ref). 

Currently, I am using: "estimate 'age' age 1 / exp;" However, this doesn't separate out by each age category. 

 I'm sure there is an easy solution but I'm not finding on online (maybe a where statement?). 

Any help is much appreciated!
