        !             3: .PP
        !             4: There are a number of
        !             5: ``system commands'' in \*a.
        !             6: These commands are used
        !             7: to control your current
        !             8: session.
        !             9: System commands
        !            10: may be typed at any time
        !            11: when \*a is prompting for input.
        !            12: (They may not be included
        !            13: in \*a functions, however.)
        !            14: As stated previously,
        !            15: when \*a is waiting for
        !            16: input from the keyboard,
        !            17: it will type eight spaces.
        !            18: .PP
        !            19: There are two types of
        !            20: system commands,
        !            21: those which request information
        !            22: and those which specify action by \*a.
        !            23: All system commands are preceeded
        !            24: by a right parenthesis.
        !            25: As an example,
        !            26: the following is a typical
        !            27: entry into \*a:
        !            28: .sp
        !            29: $ apl
        !            30: .br
        !            31: a p l \\ 1 1

        !            34: .sp
        !            35: clear ws
        !            36: .sp
        !            37:        \_
        !            38: .sp
        !            39: (the underline character ``\_''
        !            40: represents the ``cursor''
        !            41: on the terminal).
        !            42: The ``)lib'' command could then
        !            43: be typed:
        !            44: .sp
        !            45:        )lib
        !            46: .sp
        !            47: .PP
        !            48: Commands which specify action
        !            49: are composed of the command
        !            50: name
        !            51: and some other value.
        !            52: For instance,
        !            53: to set the output width
        !            54: (number of characters per line
        !            55: that \*a will print)
        !            56: to 64,
        !            57: the command is:
        !            58: .sp
        !            59:        )width 64
        !            60: .sp
        !            61: .PP
        !            62: A final warning \(em
        !            63: the command name and the right
        !            64: parenthesis must be together:
        !            65: .sp
        !            66:        ) width 64
        !            67: .sp

        !            69: .PP
        !            70: The available commands are described
