Syntax: DEVICE vaxuis [ X Y ]

   the VAXUIS driver is used to display graphics on a VAX Workstation
using the VAX UIS$ library routines. The optional X and Y parameters
specify the size of the graphics window ( in centimeters ) created on
the workstation screen.

   If called without the optional X and Y parameters the graphics 
display window will be the same size as that previously displayed.

   If the X and Y parameters are not specified the first time the
DEVICE vaxuis command is issued, the graphics display window will
occupy 1/2 the height and 1/2 the width of the workstation screen.

For example, to create a 15 cm wide x 10 cm tall display window say:
		DEVICE vaxuis 15 10
