- Entering and exiting the NeXtMidas shell:
  - After the NeXtMidas shell session has been started (by running `nmstart`) you are free to enter the shell.
  - The shell can be entered by using the `nm` command:
    - In Linux:

          $ nm
          nM>

    - In Windows:

          c:\> nm
          nM>

  - You will know that you are inside the NeXtMidas shell whenever you see the `nM>` prompt in the console.
  - Once inside the shell you are free to run any NeXtMidas commands.
  - You can exit the NeXtMidas shell by typing `exit`. You can later re-enter the shell by running `nm` again.
