 POINT {(number%) | (x%,y%)}
 
 Usage Notes
   ■ References to the POINT function are not allowed with forms and cause
     Visual Basic to generate the error message, "Invalid when forms are
     showing." Use the HIDE method to hide any visible forms or controls
     before executing this function. See: ◄HIDE Method►
 
   ■ When (x%,y%) are used to specify a pixel, the POINT function returns the
     color number of the indicated pixel. The expressions x% and y% are
     viewport coordinates; if no VIEW statement has been executed, or the
     most recently executed VIEW statement has no arguments, the viewport
     coordinates are the same as the absolute screen coordinates.
     See: ◄VIEW Statement►
 
   ■ The meaning of the color number returned as well as the valid range of
     values for x% and y% depend on the current screen mode established by
     the most recently executed SCREEN statement. If the specified pixel is
     out of range, POINT returns the value -1. See: ◄SCREEN Statement►
