Sequence Control Instructions Section 3-4
Instead of switching processing with compound conditions, insert an
MILH(517) or MILR(518) instruction before each process and an MILC(519)
instruction after each process.
Unlike the IL(002) interlocks, MILH(517) and MILR(518) interlocks can be
nested, so the operation of similar programs will be different if MILH(517) or
MILR(518) is used instead of ILC(002).
