00008 combines 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 fol-
lows:

The first logic block instruction is used to combine the execution conditions
resulting from blocks a and b, and the second one is to combine the execu-
