Detailed Description

The GAMSOptions class manages GAMS options (sometimes also called GAMS parameters since they correspond to the command line parameters of the GAMS executable) for a GAMSJob and GAMSModelInstance. There are integer (e.g. NodLim), double (e.g. ResLim), and string (e.g. PutDir) valued options. There are also a few list options (Defines to set string macros inside GAMS and IDir provide multiple search paths for include files) and a power option to set a solver for all suitable model types (AllModelTypes).

Some options known from other interfaces to GAMS that are of limited use or could even create problematic situations in the .NET environment are not settable through the GAMSOptions class.

For some options (e.g. Case) other GAMS interfaces use numeric values (e.g. 0,1) while the GAMSOptions class has enumerated types with proper names (e.g. MixedCase, UpperCase).

A GAMSOptions instance is connected to external resources and needs to be properly disposed before the .NET garbage collector can claim the instance.
