Both of the coding methods described above can also be used when using AND
LOAD and OR LOAD, as long as the number of blocks being combined does not
exceed eight.

The following diagram contains only two logic blocks as shown. It is not neces-
sary to further separate block b components, because it can be coded directly
using only AND and OR.

Although the following diagram is similar to the one above, block b in the diagram
below cannot be coded without separating it into two blocks combined with OR
LOAD. In this example, the three blocks have been coded first and then OR
LOAD has been used to combine the last two blocks, followed by AND LOAD to
combine the execution condition produced by the OR LOAD with the execution
condition of block a.

When coding the logic block instructions together at the end of the logic blocks
they are combining, they must, as shown below, be coded in reverse order, i.e.,
the logic block instruction for the last two blocks is coded first, followed by the
one to combine the execution condition resulting from the first logic block
instruction and the execution condition of the logic block third from the end, and
on back to the first logic block that is being combined.
