- Lab 1 - Macro Pipes:
  - Create a new macro called `pipeslab1.mm`.
  - Inside the macro make a pipe section.
  - The first line inside the pipe section should be: (Provides a way to stop the macro, more details about `PANEL` will be covered in the Graphics module.)

        PANEL

  - In the pipe section create a `WAVEFORM`.
    - Use `FORM=SF` and `ELEM=100k`.
    - The output should go to a pipe named `_wave`.
  - Compute the `FFT` of the waveform.
    - Use the `/DBF` switch on `FFT`.
    - The `FFT` should take in `_wave` and output to a new pipe named `_waveb`.
  - `PLOT` the output from `FFT`.
  - Now run the macro.
    - You should see a raster in the `PLOT` window.
    - To exit just click the 'X' in the upper corner of the panel.
