 ** @version  0.0.1

 ***************************************************/

// The following requirement is tested:
// If value returning functions are called in receiving communication operations (in templates, template fields, 
// in-line templates, or as actual parameters), in guards or events of alt statements or altsteps (see clause 20.2), 
// or in initializations of altstep local definitions (see clause 16.2), the following operations shall not be 
// used in functions called in the cases specified above, in order to avoid side effects that cause changing the 
// state of the component or the actual snapshot and to prevent different results of subsequent evaluations 
// on an unchanged snapshot:
// e) Calling non-deterministic external functions, i.e. external functions where the resulting values for actual 
// inout or out parameters or the return value may differ for different invocations with the same actual in and 
// inout parameters (see notes 4 and 6).
