    The follow methods checks the parameter for other functions. If a parameter or his value is non valid,
    we return "sal_False". (else sal_True) This mechanism is used to throw an ASSERT!

    ATTENTION

        If you miss a test for one of this parameters, contact the autor or add it himself !(?)
        But ... look for right testing! See using of this methods!
