   Possible.   
      
   But the shareable images given in the first post was   
   VAXCRTL in normal and G-floating edition.   
      
   And as a starting point I would assume that everything   
   in there is in DECC$SHR.   
      
   Maybe there is a VAXC$FOOBAR that is not in DECC$SHR,   
   but then we need more info.
