instruction code Divide-Erase The instruction code 'Divide-Erase' is an instruction code of the transsmt instruction set that attempts to divide off a finished offspring copy. It uses whatever memory space the write-head is currently pointing to as the offspring's genome. If this instruction code fails, the memory space is cleared and the organism's heads are reset. Note that this instruction code is equivalent to the instruction code 'h-divide' of the heads_default instruction set.
