31577: Orders-menu build, lower part
Tail of the orders-screen build started in InitGameView (31417). First the third-boundary case of the crew-name row stride (+1824), then the shared loop tail: store the draw pointer, advance A' to the next crew id and loop until all 7 names are printed. After the loop, draws menu rows 9-18 straight from OrdersMenuLowerHalf (30205) (" Indicate "/" Location ", " Display "/" Level ", the three deck rows, blanks), re-highlights the cursor row and mirrors its cell value (34882), and redraws the oxygen clock on row 19 (39572).
