F0D2: Wait for no key, then for a key
Used by the routines at TITLE_SCREEN, ROOMST and MAIN_LOOP.
The author's WAIT; PAUS, at offset 6, is the second half alone, a wait for a key. Both read all eight half-rows at once (A=0 selects them all), so any key will do. WAIT is used after GAME OVER (TITLE_SCREEN), at the end of the quest (ROOMST) and for the pause, SPACE with SYMBOL SHIFT (MAIN_LOOP); PAUS under the title.
