Other instructions can be input between the MILC(519) instructions, as shown
in the following diagram.
If there is an ILC(003) instruction between an MILH(517) and MILC(519) pair,
the program section between MILH(517) and ILC(003) will be interlocked.

Other instructions can be inserted between

sections A1 and A3 operate together. (They
are interlocked when "a" is OFF, regardless
of the ON/OFF status of "b".)

the interlock is cleared at that point.
