Displays PICT with the specified

coordinate at the upper left corner of

the graphics display.

PX->C

Converts a pixel coordinate

C #Hx #Mv > to a user-unit coordinate

C-.PK

(To graphics object.) Converts an

object (level 2) into a graphics object

using real number n (0 to 3 from

level 1) to specify the character size.

The resultant graphics object is a string

of small (n=l), medium (n=2), or large

(n=3) characters. For n=0, the

character size is the same as for n=3,

except that for algebraic and unit

objects, the resulting graphics object is

the EquationWriter picture.

BLANK

Creates a blank graphics object on the

stack of size #»x (in level 2) by #«y (in

level 1).

3 graphics object. The upper left corner

of the level 1 graphics object is

positioned at coordinates specified in

level 2.

GXOR
