   Sorry, but I wont bite. You're trying to shoehorn the mainframe into a box.   
      
   Take the following code, all executed on the same platform, in the same CSECT:   
      
                   SAM24   
                   LA 1,x'1'   
                   SAM31   
                   LA 1,x'1'   
                   SAM64   
                   LA 1,x'1'   
      
   There is no 'bitness' to the executable produced by assembling the above code.   
   The LA instruction doesnt change 'bitness', it is still LA.
