We could dispense with base-displacement requirements for branching by
using the 'branch relative' instructions. The trouble is that there is a
PTF requirement for HLASM as well as a certain minimum as far as CMOS
processors are concerned. All base-displacement branch instructions have
their 'relative' replacements. The extended mnemonics are JZ,JNZ,....
I've forgotten what the corresponding BXLE,... mnemonics are. This frees
up registers to be used for more important things.
