And like 'menu', the selected option is consistent with grouped options

-'prompt' works almost the same as select, except that when a character

+*prompt("<option>"{, "<option>", ...})
+
+This function behaves exactly like select(), but when a player presses cancel
+it returns 255 and the script is not terminated. You almost always want to use
+select() rather than prompt().
