I assume that you are using mathprog and then producing an MPS file for
CBC, and as you point out, you can't then use the mathprog output
statements and would have to process the results some other way.

Are you able to share the details on how you make this work? I presume
CBC is the COIN-OR MIP solver. How is easy is CBC to work with and how
do you handle the output processing?
