Subject:	How do I grab the screen and then put it back?

Hi all,
	I am using the GRX graphics package and I am writing a rendering program. At the moment it draws wireframes, constant shaded and Gouraud shaded objects.
I would like to be able to grab the screen somehow (temporarily), then print
up some info, help, etc. and then restore the screen to its original picture.

	Is there a quick, easy way to do this using GRX?

Any help much appreciated, many thanx in advance.

Charlie.
