How to find a certain string in a file and replace it with a value from another file using sed/awk?

Guys thanx for replying!!
But will these solve my problem? since where exactly are we searching the string 'OUT' here? I actually have similar other strings to search and replace with other values from other files.. actually this is the case:
file 1:
(define argc :: int)
(assert (> argc 1))
(assert (= argc ARG))
<check>
(define argc :: float)
(assert (> c 0))
(assert (= c OUT))
<check>
.
.
.
file2:
main 1
file 3:
main 0
.
.
.
Now, I have to find the string 'ARG' from file 1 and replace it with the value '1' from file 2. And, find 'OUT' and replace it with the value '0' from file 3.
Now can you put some more light on it?
