    """Specifies the annotation number, type, and hot spot (GUI).

    APDL Command: /ANUM

    Parameters
    ----------
    num
        Annotation number.  ANSYS automatically assigns the lowest
        available number.  You cannot assign a higher number if a lower
        number is available; ANSYS will substitute the lowest available
        number in place of any user-specified higher number.

    type\_
        Annotation internal type number.  If TYPE = DELE, delete annotation
        NUM.

        1 - Text

        2 - Block text (not available in GUI)

        3 - Dimensions

        4 - Lines

        5 - Rectangles

        6 - Circles

        7 - Polygons

        8 - Arcs

        9 - Wedges, pies

        11 - Symbols

        12 - Arrows

        13 - Bitmap

    xhot
        X hot spot (-1.0 < X < 2.0).  Used for menu button item delete.

    yhot
        Y hot spot (-1.0 < Y < 1.0).  Used for menu button item delete.

    Notes
    -----
    This is a command generated by the GUI and will appear in the log file
    (Jobname.LOG) if annotation is used.  This command is not intended to
    be typed in directly in an ANSYS session (although it can be included
    in an input file for batch input or for use with the /INPUT command).

    Type 13 (bitmap) annotation applies user defined bitmaps defined using
    the FILE option of the /TXTRE command.

    This command is valid in any processor.
