There isn't any real limit that I am aware of, except for the memory overhead
and practical limitations of what your computer can handle.
I would like to recommend however that, instead of reading the contents of
your files into memory and then calculating the results after the fact, you
might want to perform your comparisons as you go. For instance:
open IN1, "file1";
open IN2, "file2";
while ($line1 = <IN1> and $line2 = <IN2>) {
# compare $line1 to $line2
}
close IN1;
close IN2;
This of course depends on what these files contain, and what you are trying to
compare.
