IMsCompositeFormulaTermSetList.Count

Syntax

Count: Integer;

Description

The Count property returns the number of sets in the collection.

Example

Executing the example requires that the repository contains CONT_MODEL modeling container with the BINREG model that uses the binary regression method for calculation.

Add links to the Metabase and Ms system assemblies.

       Debug.WriteLine("  Set " + (i + 1).ToString + ":");
        For j := 0 To TermSet.Count - 1 Do
            CompTerm := TermSet.Item(j);
            Debug.WriteLine("    " + CompTerm.ExpressionText);
        End For;
    End For;
    Debug.WriteLine("Number of sets used for model calculation: " + Explanatories.IncludedCount.ToString);
End Sub UserProc;

After executing the example sets of explained series terms are displayed in the console window. The number of sets used for model calculation is also displayed.
