Current Page: NeXtMidas Training Primitives Special Variables List of Variables MQ, MR, MW
- | The current `MessageQueue` (`MQ`): Used to send a Message. (More will be said about this later.) The `Results` table (`MR`): Can get and set (put) results. Yes, that's about it.
      MR.put("KEY", "results value");
      MR.put(rename, calculatedValue);
The `MWindow` (`MW`) (graphical primitives only): Handle to the graphics library being used. (Not covered in this module.)
X-Midas Users Take Note:
Since NeXtMidas makes it easy to create real-time controls that alter variables held privately inside a primitive (shown later in this module) there is rarely a need to access results parameters from a primitive except to store the results of a computation (which is always done in the `close()` method). As a rule NeXtMidas primitives never poll the values of results parameters.
