Program read answers from a OS file

Hi,
I want to automate a menu based program for which I don't have the source

If I run it interactively I do this:
do ^<program>

It presents a menu and then you can go down further menus

Based on the selection it may ask for answers to other questions.

Is there some way I give the program a "response" file?

If not would I be able to use I/O redirection for this task?
Inputs would come from a file.
Output should go to the terminal (so I monitor how far the process has gone)

I have seen some examples of redirection code and it seems quite complicated.
