The loop 3) is repeated 4 times.
When the data value (current value) of D0Z
(D4 when Z is "4") is "6", the loop 2) is
repeated 6 times.
When X010 is OFF
When K1X000 is "7", the loop 1) is repeated 7 times.
When X010 is ON
The program execution jumps to the pointer P22, and
the loop 1) is skipped.
Number of times of repeating the loops 1), 2) and 3).
