Ok i tested it.
It looks like that
C:\Documents and Settings\manu\Desktop\bi>start echo 1 | birth.exe
 - Start
 - Exit
and a second dos window is open with this
C:\Documents and Settings\manu\Desktop\bi>
And when i tip 1 on my keyboard it starts the Program
So i think that i hast to start the programm and then use echo 1
I tryied but it doesnt work.
How can i write the echo after start tr.exe?
