I need to put in some code in a dos batch to tell the user to enter 1, 2 3 or 4 on the keyboard.
This runs the batchjob to put in a specific code into a website with JAVA.
There is a little box with a user-id and i need to put the users id in that box automatically.
Can it be done somehow?

I know the "DOS" code is wrong in this forum, but where to put this tread then?

Hope someone can help me.
