Often you will want to use a Visual Basic primitive type, such as Boolean or String, as a type for a Flow Port in a SySim Simulation Scenario.

To use a Visual Basic primitive type as a type for a Flow Port, use a Value Type as the type of the Flow Port and ensure that the Value Type has the same name as the Visual Basic primitive type.

The SySim Profile provides some Value Types for common Visual Basic primitive types. These Value Types reside in the SySim Profile::SySim DataTypes package.

To create an additional Value Type to represent a Visual Basic primitive type: Create a Package outside of the SySim Profile package and apply the «SySim Predefined» stereotype to that Package. In that Package create a Value Type and set its name to that of the Visual Basic primitive type you want to represent. Apply the «SySim DataType» stereotype to that Value Type.
