在我的VBA程序中为excel; 我有一个名为"ParamCheck"的函数,它获取四个"双"变量,检查它们并返回一条消息"string".

Function ParamCheck(airSpeed As Double, FCUvalue As Double, _
            altitude As Double, terrainElevation As Double) As String

            If airSpeed < MIN_CONTROL_SPEED Then                            
            'check if airspeed is less than 119 ft/min or not
                ParamCheck = "Airspeed is less than minimum control speed"

            ElseIf FCUvalue > FCU_VALUE_LIMIT Then                          
            'check if FCU value if greater than 10 or not
                ParamCheck = "FCU value is greater than limit"

            ElseIf FCUvalue < 0 Then                                        
            'check if FCU vlaue is negative or not
                ParamCheck = …
