    There are also Windows ports of the old DOS CRT unit if to you need it to be more flexible. Search for wincrt.

    Zhan Wang Also you can write #13 to move cursor to the beginning of line:
    program Project1;
    {$APPTYPE CONSOLE}
    begin
    Write('Some text');
    Write(#13'New text');
    Readln;
    end.

    Try my Console unit. It has GotoXY, WhereX, WhereY, ClrEol, ClrScr, etc.: rvelthuis.de - Rudy's Delphi Corner - Console unit
