Hey guys, thanks again for all of the help. I believe I have figured out a lot of the silly errors I was making, and have a more general question. I am using a hash for the same data file as I showed before: 
777666555 Smith Tom RM So
111222333 Jones Mary SD Fr
555444333 Johnson Lee IE Sr

I am reading it in from the file, and using split, am extracting the first piece of data (the ID) to be the hash key, and the remainder to be the values. Here is the snippet: 
while(my $line2 = <INPUT>){
    chomp($line2);
    my @splitStudent = split(' ', $line2);
    $size = @splitStudent;
    my $keys = splitStudent[0];
    my $Lname = splitStudent[1];
    my $Fname = splitStudent[2];
    my $Major = splitStudent[3];
    my $Year = splitStudent[4];
}
my @IDSorted = sort(keys(%student));

However, I do not understand how to store the data from the entire file. It seems to me that this code would work only to read in one line. My problem arose when later, I am taking user input to determine if it matches a key...then, if so, outputting each piece of data corresponding to that key. How exactly would I obtain the Fname, Lname, and so on...in order to print?
