Blocks a1 and a2
Blocks b1 and b2
Blocks a and b
This type of diagram can be coded easily if each block is worked with in or-
der first top to bottom and then left to right. In the following diagram, blocks a
and b would be combined with AND LD as shown above, and then block c
would be coded and a second AND LD would be used to combine it with the
execution condition from the first AND LD, and so on through to block n.

The following diagram requires first an OR LD and an AND LD to code the
top of the three blocks, and then two more OR LDs to complete the mne-
monic code.
