Relative Risk for continuous predictor PROC GENMOD

[Novice_user]

Hi All, 

Sorry if this is a terribly simple question but I have looked north and south and can't seem to find an answer.  I have a very simple model with one continuous predictor and an outcome variable, and want to get a relative risk to say that for each unit increase in x the relative risk for y increases by z amount.  Is there a way to get the point estimate and 95% confidence interval for a continuous variable equivalent to the 'estimate 'Beta' trt_group 1 -1 / exp' statement for categorical predictors?

PROC GENMOD DATA=Have

MODEL y = x/dist=bin link=log;

RUN;

Many thanks
