- Using `EXPLAIN <command>`:
  - Every command has an explain file that explains how to use the command.
  - You can read the explain file of any NeXtMidas command by typing `EXPLAIN` `<command>` and the command name after the NeXtMidas prompt. For example:

        nM> expl BEEP
        BEEP - Emits an audio beep.

        <func>  - ON|OFF|n, where n = number of beeps
        <delay> - Delay between beeps [SECS] (<func> = n only)

        Causes the system to beep. The <func>=ON and <func>=OFF
        may be used to turn ON/OFF verification beeps after a
        command is executed (these have the same effect as using
        "VERIFY ON BEEP" and "VERIFY OFF BEEP").

        Examples:
          nM> beep 2 2 ! Beep 2 times with 2 seconds between beeps.

          nM> beep on  ! Beep after completion of each command.
