<sect1>Keyboard codes<p>
For direct keyboard scanning in conjunction with e.g. the OS location "CH" (764/$2FC),
all keyboard codes are available as defined values on C and assembler side.
Example:
<verb>
...
while (!kbhit());
switch (PEEK(764))
{
case KEY_RETURN:
...
case KEY_SPACE:
...
case KEY_1:
...
}
...
</verb>
You can find the C defines in the file "<tt/_pokey.h/" or "<tt/atari_pokey.inc/" for the assembler variant.
