 point
 define a point Calling Sequence point(P, Px, Py) point(P, [Px, Py]) Parameters

 P - the name of the point Px - the horizontal coordinate Py - the vertical coordinate Description

 • A point is represented as a dot. It has position only, and has no length, width, or thickness.
 • A point P is represented by its horizontal coordinate Px and vertical coordinate Py.
 • To access the information relating to a point P, use the following function calls:

 form(P) returns the form of the geometric object (i.e., point2d if P is a point). coordinates(P) returns [Px,Py] where Px is the horizontal horizontal coordinate and Py the vertical coordinate of P. HorizontalCoord(P) returns Px which is the horizontal coordinate of P. VerticalCoord(P) returns Py which is the vertical coordinate of P. detail(P) returns a detailed expression of the point P.

 • The command with(geometry,point) allows the use of the abbreviated form of this command. Examples

 > $\mathrm{VerticalCoord}\left(B\right)$
 ${0}$ (5)
 > $\mathrm{detail}\left(B\right)$
