It is going to be the exponentiated difference between the lines at
specified points. This can be done using proc genmod. IF you need a
codelet let me know.

Subject: Interaction between categorical and continuous variables in
regression model
Dear all,
I had a problem to test interaction between categorical and continuous
variables in regression model.
The regression model is like this:
Disease (Y/N)=Exercise (Y/N) Caroric_intake (1500 to 3000)
Exercise*Caroric_intake
I need to estimate the disease risk (OR and CI) and calculate P
values.
Any suggestions or comments?
Thanks,
Andrew
