If a right-hand instruction requires multiple instruction lines, all of the lines for the
instruction are entered before the right-hand instruction when inputting in mne-
monic form (although this is not always true when inputting using ladder dia-
grams). Each line of the instruction is coded first to form ‘logic blocks’ combined
by the right-hand instruction. An example of this for SFT(050) is shown below.
00000 LD 000000
00001 AND 000001
00002 LD 000002
