The following diagram requires five blocks, which here are coded in order
before using OR LOAD and AND LOAD to combine them starting from the
last two blocks and working backward. The OR LOAD at program address
008 combines blocks d and e, the following AND LOAD combines the result-
ing execution condition with that of block c, etc.
Block d

0106 0107
Block e
Again, this diagram can be redrawn as follows to simplify program structure
and coding and to save memory space.
