             GIST_FORMAT  
 
   NOTE: gist is deprecated; postscript output is now the default  
     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";  

 Y_HOME  
 

 Y_LAUNCH  
 

             Y_LAUNCH       the directory containing the Yorick executable  
             Y_SITE         Yorick's "site directory" (platform independent)  
             Y_HOME         Yorick's "home directory" (platform dependent)  
 
     Y_LAUNCH is set by compiled code when Yorick starts and should never  
              be modified.  
     Y_SITE is set to a default built-in value by compiled code at startup,  
              but may be modified in the file Y_LAUNCH/paths.i to allow for  
              ports of Yorick binary executables.  
       contains subdirectories i0/, i/, i-start/, and others  
     Y_HOME is set to a default built-in value by compiled code at startup,  
              but may be modified in the file Y_LAUNCH/paths.i to allow for  
              ports of Yorick binary executables.  
       contains file Make.cfg, subdirectories i-start/, lib/, and others  
     if the compiled-in value of Y_SITE is incorrect (i0/std.i missing),  
     then both Y_SITE and Y_HOME are reset to Y_LAUNCH/.., which allows  
     relocatable yorick distributions
