For this question to be even mildly interesting, it has to be assumed that
simple redirection (i.e., program > file) and then parsing the resulting
file is not an option. This can happen in the real world with programs
that, for whatever reason(s), insist on writing to the screen and won't
send their output to a file via simple redirection.
Assuming this to be the case, then you will have to come up with a way to
pick off the information from the screen itself. AFAIK, there is no way to
do this in pure batch, but it is easy enough done using some "real"
scripting language; one that can access and execute the
ReadConsoleOutputCharacters() API. I know how to do this (and have done
so) in WinBatch. I'm sure some enterprising soul will come along and tell
you how to do it in VBScript (or whatever they are calling it nowadays).
