    I study on a mixed integer linear programming formulation and I coded this forulation using OPL 6.3. Now I am trying to extract my model to LP format. I need to check the model in details from the LP document. But, when it comes to run with LP format, I get an error which has noname or description. How may I solve this problem please let me know.

    Kindly regards...
