The pseudo code should be like this ?
===============
KeyScan:
1.Start
2.scan the key
3.If not down goto step 7
4.Wait for 20-50ms
5.key still down? If not goto step 7
6.excute keydown statements
7.exit

Call KeyScan every 100mS or as required.
================

thanks for correction.

but what i assumed is master lio will call that routine after a key interrpt has happenned and now he has to check what key has been pressed and the validity of the keystroke.
