Hi, I am passing two arrays to a subroutine and getting some wierd results. Here is my code snippet 
@MLR_file = <MLR>; # read in file 1 data
$MLR_file[2] =$MLR_file[1] = $MLR_file[0]; # modify it

@MLR_file2 = <MLR2>; #read in set2 data
$MLR_file2[2] =$MLR_file2[1] = $MLR_file2[0]; # modify it

&printFile (@MLR_file, @MLR_file2);

sub printFile {

#print the contents of each array to the correct ouput file
    my @file = $_[0];
    my @file2 = $_[1];

    foreach $line(@file) {
        print OUT "$line";
    }

    foreach $line(@file2) {
    print OUT2 "$line";
   
    }

Basically I'm reading files into an array, modifying them, and writing the new output to a new file. The trouble is that my new output file(s) only has one line in it (there should be 96 lines of output).

I tried passing the arguments as references, without really know why. When I more my ouput file(s) looked like this 

ARRAY(0xd3a2c)
ARRAY(0xd3a98)

Any explaination on this would be appreciated. Thank you.
