37 * This is the direct console interface for cc65. I do not like the function
38 * names very much, but the first version started as a rewrite of Borlands
39 * conio, and, even if the interface has changed, the names did not.
41 * The interface does direct screen I/O, so it is fast enough for most
42 * programs. I did not implement text windows, since many applications do
43 * not need them and should not pay for the additional overhead. It should
44 * be easy to add text windows on a higher level if needed,
46 * Most routines do not check the parameters. This may be unfortunate but is
47 * also related to speed. The coordinates are always 0/0 based.
