I've had to do this a couple of times but never in recent years. I
don't know your exact needs, but the best tool I ever found for this
sort of job was called Phantom of the Keyboard.

I ran into a couple of apps that I needed data out of and couldn't get
it. They'd only output to screen, never to disk. I used Phantom to
automate the app to dump data to screen and then capture the screen to
disk.
