Questions in Assembler - Created a PIANO wheee :)

[FlipMode]

I have a problem in my piano program -
i want to make a part in my program that is responsible for the color change in the piano keys in such a way that AS LONG AS A KEYBOARD KEY IS PRESSED that piano key that is related to the keyboard key will be BLUE (creating a delay that is reacting to the key press, or something) and the moment the finger is released from the key - it will turn white again.
i dont know how to create such a delay - now im using a fixed delay which is no good at all... sometimes when i press the same key twice fast it doesnt show the blue thing appropiately
besides that i need help in many more things... if someone will be willing to help me - i will appreciate it very much

thank you in advance
amit

The thing that may help you is to use ports ....

if you know pascal this would be it ... the asm is not much different


Program test_keybp;
begin
repeat
Witeln(port[$60]);
until port[$60] = 1;
end.


this program will loop ..until you press ESC
and write the codes of the key(s) pressed...

you can say :

make_blue;

while port[$60] = xxx do begin
{stay blue, or do something}
end;

return_to_white;


the instruciton in ASM is IN for reading and OUT for writ...

There is a problem with this ...you need to find a way to tell
the comp. that you handled the key change or it will beep ...
like hell..
how to do that I do not know..


sorry for the way I wrote this, no time for decorations

I forgot, the $60 (60h) is the "place" where the status
of the keyb. is kept... so any change will be noticable by
comparing ...


I will post the code ... as soon as I get my hands on masm
or pascal, tried to do a .com in debug.exe but I love my
self and my self and decided not to.

some port near that tells that you handled it.
