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 00008 com-
bines blocks blocks d and e, the following AND LOAD combines the resulting
execution condition with that of block c, etc.

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

The next and final example may at first appear very complicated but can be
coded using only two logic block instructions. The diagram appears as follows:
