Selects scenario index of multi-scenario models
 Type: int
 Default value: 0
 Minimum value: 0
 Maximum value: MAXINT

When working with multiple scenarios, this parameter selects the index of the scenario you want to work with. When you query or modify an attribute associated with multiple scenarios (ScenNLB, ScenNUB, ScenNObj, ScenNRHS, etc.), the ScenarioNumber parameter will determine which scenario is actually affected. The value of this parameter should be less than the value of the NumScenarios attribute (which captures the number of scenarios in the model).

Please refer to the discussion of Multiple Scenarios for more information on the use of alternative scenarios.

One important note about integer-valued parameters: while the maximum value that can be stored in a signed integer is <span>$</span>2^{31}-1<span>$</span>, we use a MAXINT value of 2,000,000,000. Attempting to set an integer parameter to a value larger than this maximum will produce an error.
