Coding Right-hand Instructions Section 5-5
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.
