Below is the example of using the GetMs operation to calculate an equation. The request contains and instance of opened modeling container, equation calculation pattern, and parameters of operation execution. The response contains an instance of the model that contains an equation with calculation results.
To execute the example, the equation must be calculated with the Determinate Equation method.

The GetMsDeterm function calculates the specified equation. Input parameters:
ms. Opened modeling container instance.
modelKey. Key of the model that contains the equation.
eqKey. Equation key.
After executing the function returns a model that contains calculated equation. Calculation results are displayed in the console window. The following auxiliary procedures described in the Calculating Equation section are used to output the results: PrintArray and PrintSeries.
To execute the example, the equation must be calculated with the Determinate Equation method.
