This is the identifier to specify the memory area number. It is expressed by affixing “K” to the

assigned with “K0,” this represents that control area is specified.
The memory area now used for control is called “Control area.”
If the memory area number is not specified when selecting the identifier corresponding to
the memory area, selecting is made to the memory area.
If any identifier not corresponding to the memory area is assigned with a memory area
number, this memory area number is ignored.
