The window control area allocations are shown in the following table.
NS Series pop-up screens do not distinguish between global windows and local windows like the NT
Series. The pop-up screens are handled as pop-up screen 1 (k to k+2), pop-up screen 2 (k+3 to k+5),
and pop-up screen 3 (k+6 to k+8), based on the order they are opened.
