Multiple Instruction Lines If a right-hand instruction requires multiple instruction lines (such as KEEP(11)),
all of the lines for the instruction are entered before the right-hand instruction.
Each of the lines for the instruction is coded, starting with LD or LD NOT, to form
‘logic blocks’ that are combined by the right-hand instruction. An example of this
for SFT(10) is shown below.
