HP 38g Graphing Calculator - Manual (Page 167)

The Graphic commands use the graphics variables G0-G9 as
name arguments—or the Page variable from Sketch. Position
arguments take the form (x,y). Position coordinates depend
on the current aplet's scale which is specified by Xmin, Xmax,
Ymin, and Ymax.
Graphic Commands

^GROB Creates a graphic from e x p r e s s io n , using fo n t_ s iz e , and stores
the resulting graphic in n a m e . Font sizes are 1, 2, or 3. If the
fo n t_ s iz e argument is 0, the HP 38G creates a graphic display
like that created by the SHOW operation.

GROBNOT Replaces graphic in n a m e with bitwise-inverted graphic from
n a m e .
