Nesting (N)

Nesting (N) is a device used in the master control instructions (MC and MCR instructions) to program operation
conditions in a nesting structure. The master control instruction opens or closes a common ladder gate to efficiently
switch the ladder of a program. Specify the nesting (N) in ascending order (in order of N0 to N14), starting from the
outside of the nesting structure.
