clear. Three keys are missing between steps 02 and 03.

Missing three steps ( [ ], 3
and (6]) here.
In order to add the missing steps we need to branch to one of the
available program steps in program memory. The corrected
program is shown below.

Notice in particular that the instruction originally stored in step
02 is now stored in step 10. Step 02 now contains an uncondi-
tional branch instruction to step 10. The missing keys are stored
in steps 11 through 13 and the instruction stored in step 14 is an
unconditional branch back to step 03 in the main program.
