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