Well, the "problem" here is that readkey() returns an integer with
information in the lower 16-bits. The high byte of this contains the
scancode, i.e. ESC = 1 and so on. The low byte contains the Ascii
character, so converting this to a char is neccessary if you just want the
character. This is covered in the docs too AFAIK, read them! :)
