Visual Basic Example:

     Dim MPL As OptiMax
     Dim cpxSolver As Solver
     Dim solvOption As SolverOption

     Set MPL = New OptiMax

     ' Load CPLEX solver into memory
     Set cpxSolver = MPL.Solvers.Add("c:\mplwin4\CPLEX65.dll")

     CpxSolver.Options("IterationLimit").Value = 1000

     For Each solvOption In cpxSolver.Options
         Debug.Print "CPXOPT: " & solvOption.Name & ": " &
         " val=" & solvOption.Value & _
         " def=" &   solvOption.DefaultValue & _
         " max=" & solvOption.MaxValue & _
         " min=" & solvOption.MinValue
     Next solvOption
