SYSTEM

        [SIC\]SYSTEM ["Command"]
        $ Command

    Execute a command from the operating system, or create a subshell. If no
    argument  is  given, start a subshell by running the default user shell.
    The subshell can be terminated by typing 'exit' or  'bye'  or  'logout',
    depending on system version, and controls return to SIC in this case.

    If an argument is given, executes the command in a subshell.

    Note  that  Unix  environment variables cannot be defined in such a way,
    since it is a subshell. In  particular,  use  command  SIC DIRECTORY  to
    change your working directory.

        $ Command
    System  commands  can also be executed directly from the SIC level using
    the $ token. "Command" must be a valid operating system command  in  the
    default shell of the user.
