| All dynamic link calls are available to an application if the MachineMode value indicates the program is in OS/2 mode. This method provides a self-tailoring application that allows the application to adapt to the execution environment by limiting or enhancing the functions it provides. | All dynamic link calls are available to an application if the MachineMode value indicates the program is in OS/2 mode.
