RASTER

To invoke:	RUN  $RAS		[if not installed]
		RAS			[if installed]
		RAS  @filespec		[for indirect command file]
		RAS  PTX		[one copy to Printonix]
		RAS  IDS		[one copy to PRISM printer]



   Commands are issued in response to the command prompt RAS>, and are at
least 2 characters long, terminated by a space.

Commands:

	LIst				list the current settings
	OUtput_device   ddn:		change the output device
	COpies 		 n		change the number of copies to print
	RAster_file  	filespec	change the output raster file name
	OPtions	  	 n		bit pattern describing the options:
		  	 0		output the raster data directly
		  	 1		make a raster file
			 2		print a raster file
			 4		delete raster file when done
			10		spool the raster file for output
	SCale		 n		sets the global scale function
	OFfset		x,y		sets the global offsets
	VEctor_file	filespec	changes the input vector filespec
	V0		filespec	same as above
	V1		filespec	opens another vector file
	 :		 :
	V9		filespec	opens the tenth vector file
	S0		 n		sets the scale factor for the n'th
	 :		 :			vector file
	 :		 :		
	S9		 n
	O0		x,y		sets the offsets for the n'th vector
	 :		 :			file
	 : 		 :		
	O9		x,y
	PTx				set up for Printronix raster
	IDs				set up for PRISM raster
	GO				make/plot raster data
	GO		 n		send vector data to vector device n
	G?				list the known vector devices
	AG		n=ddn:		reassign physical vector device n


Scaling and offsetting the vector data is all done in inches, in physical
space.  The formula is as follows:

physical x,y = global_scale*(vector_scale*(x,y)+vector_offset)+global_offset
