   "I wish to run 32 bit s390 programs,    
   unmodified, at the 4 GB location."   
      
   Not possible. First off there is no such thing as a 32-bit s390 program. The   
   instructions BXLE and BXH on the s390 perform signed arithmetic to accomplish   
   their purpose.    
      
   This precludes 32-bit on the s390.   
      
   "The word "index" in the names of these instructions indicates that  one of   
   the major purposes is the incrementing and testing of an index value. The   
   increment being a signed binary integer, may be used to increase or decrease   
   the value in general    
   register R1 by an arbitrary amount."
