Well... Then welcome to this century of programming ;)
Do you want to work a GUI or a console application? If the former then you
should take a look at the OnKeyPress/-Up/-Down events of the various GUI
components. For a console application you should look at the Mouse and
Keyboard units which abstract mouse and keyboard access in a platform
independent way. Using assembler to access keyboard and mouse is not
possible on any modern OS.
