             GIST_FORMAT  
 
     is used by the hcp_out function to generate the system call which  
     invokes the gist CGM browser and pipes its output to lpr.  This  
     format should contain a single %s specification; after this %s is  
     replaced by the name of the CGM file, Yorick invokes the system  
     command on the resulting string.  
     LPR_FORMAT is also used by hcp_out to process PostScript files  
     made directly by Yorick.  
     The default values are:  
        GIST_FORMAT= "gist %s -f | lpr";  
	LPR_FORMAT= "lpr %s";
