- The `PANEL` Command:
  - The `PANEL` command is used to create a panel.
  - The `/SETUP` switch tells the panel to look for a setup file.
    - It is assumed that the setup file is named `<macro name>.mmp`.
    - If the setup file is not found, a default setup will be provided and you will be allowed to configure it at that time.
    - There are options for having more than one setup file, see the `PANEL` explain file for details.
  - The `/CONTROLS=GC` switch tells `GCONTROL` to put a reference to all of the GControls in a table called `GC`.
  - Most of the time a panel is created on the first line of a pipe section using the line:

        PANEL/SETUP/CONTROLS=GC
