APP console in Delphi3

I ask my question an other time!

In Delphi 3, we can execute program .PAS in a window, with the directive
        {$APPTYPE CONSOLE}.

What are the equivalents in Delphi3 of the Pascal following instructions
(and the units necessary):

        clrScr, delay, readKey, gotoXY.

Thank you,
