Ok, just a couple of points:
- In graphics mode, there is *no* cursor position. Any position that
you want you have to work out yourself.
- So, what you do is decide where you want the text to appear on the
screen. So make an x and y coordinate for that. Then whenever you read
a key, display it at that x and y and add 10 pixels to the x.
- You'll have to handle some keys specially, most notably the enter key
and the backspace key.
- If you want to check the actual input, add code for that
appropriately.
At least, thats how it worked last time I worte this type of code
(a while ago now).
Hope this helps,
