Another weird thought from me. In order to more easily convert to "baseless" 
coding, IBM created the IEABRCX instruction to convert all the 
base+displacement branch instructions to the corresponding relative 
instruction. As best as I can tell, the majority of the IBM macros still use 
the "short displacement" instructions. So I'm wondering if it would be helpful 
to others if IBM wrote another macro, similar in concept to IEABRCX, which 
implemented "long displacement" substitutions, via OPSYN, for those 
base+displacement instructions which have "long displacement" variants.
