reading value from a file in batch script

Question

We can set the value of a variable (say, "upper_bound") in a batch file in the following way:

SET upper_bound=3

But is there any way to read this value '3' from a input.txt file which will just contain value 3?

Please provide a more clear example of what will be in the input.txt file. — Squashman, Oct 27 '16 at 15:59
