%yes y y y (Ctrl+C) % yes .... now i will talk about something about "yes" utility... in linux,, usually located at /usr/bin/, there is a file called "yes" it utterly does nothing but continues output of "y" the size of this file is around 19kb (in OpenSUSE 11) i recommend you try this command... hehe... don't login as root,,
    yes | rm -i *
now,,, i'll talk about making "yes" on windows .... here is the one purely done in "debug" Yes >
this yes quits when you press "Q" or "q" or you can write one by a simply loop

    loop:
          mov dx, offset yes
          mov ah, 9
          int 21h
          jmp loop
    yes db "yes", 0d, 0a, "$"
or in batch file

    :yes
      echo yes
      goto yes
or if you write a keypressed.com which returns the key to command line...
