  Some changes to support early branching: branches are now ADD #x,PC instructions
  instead of MOV #x(PC),PC--providing greater range to the CPU. When that range
  is insufficient, ZPARSER now recognizes long jump instructions coded as
  LOD (PC),PC followed by the jump address. (This change was made necessary by
  the need to build an assembler/linker that could create instructions that would
  jump to any address in the 32-bit address space. In short, a part of the
  ongoing GCC upgrade and rework.)
