View Variable Values

This section describes the procedure of displaying variable values in the console window.

In the modelling example, after problem calculation results were loaded to the Balance of Trade, billion USD variable by the Fact scenario. The module described below is used to view these results.

To run the module of viewing calculation results, the user needs to add links to the Ms, Metabase,Cubes,Dimensions,Matrix assemblies.

Sub Main;

Var

MB: IMetabase;

KMDesc: IMetabaseObjectDescriptor;

Problem: IMsProblem;

VarList: IVariableStubList;

VarStub: IVariableStub;

VarObj: IMetabaseObject;

CubeInst: ICubeInstance;

Des: ICubeInstanceDestination;

DimSS: IDimSelectionSet;

DimS: IDimSelection;

Elem: IDimElementArray;

Mat: IMatrix;

Coord: IMatrixCoord;

i: Integer;

Begin

MB := MetabaseClass.Active;

KMDesc := MB.ItemById("MODEL_SPACE");

Problem := mb.ItemByIdNamespace("PROBLEM_BALANCE", KMDesc.Key).Bind As IMsProblem;

// Get output variable

VarList := Problem.VariableStubs(MsVariableKind.Output);

VarStub := VarList.FindById("BALANCE");

// Get variable view in express analysis

VarObj := (VarStub As IMsVariable).Cube As IMetabaseObject;

CubeInst := VarObj.Open(Null) As ICubeInstance;

Des := CubeInst.Destinations.DefaultDestination;

DimSS := Des.CreateDimSelectionSet;

// Select data frequency: Annual

DimS := DimSS.Item(0);

Elem := DimS.Dimension.Levels.Item(0).Elements;

For Each i In Elem Do

DimS.SelectElement(i, False);

End For;

// Select the Fact scenario dictionary

DimSS.Item(1).SelectAll;

// Get matrix of variable data

Mat := Des.Execute(DimSS);

Coord := Mat.CreateCoord;

Coord.Item(1) := 0;

// Display matrix with data in the console window

Debug.WriteLine(Data of variable + VarStub.Name + :);

For Each i In Elem Do

Coord.Item(0) := i;

// Mat.Item(Coord) := Math.RandBetween(50, 100);

Debug.WriteLine(Mat.Item(Coord));

End For;

End Sub Main;

After executing the example results of problem calculation loaded to the Balance of Trade, billion USD variable are displayed in the console window.
