in thread complex input file

Roger , I am new to perl . Would you mind explaining this part to me in your first answer : 
print "\t$_->[0]\t$_->[1]\n";

[download]
since if I add one more column in the DATA file , I do this : 
 
print "\t$_->[0]\t$_->[1]\t$->[2]\n";

[download]
but the output stay the same , I don't get the last column. Sorry for asking tooo many questions

    print "\t$_->[0]\t$_->[1]\t$->[2]\n";

    Contains a typo, it should be:

    print "\t$_->[0]\t$_->[1]\t$_->[2]\n";

    $_ is a special perl variable.

[d/l]
[select]
      I fixed it but not sure if we are reading up to three column at the top ,, all I did is changing the DATA to 
      
EmpNum  LOCATION  Shift  Hours
23        54        1     2
11        65        3     5
23        54        2     7

      then I modify it to 
      print "\t$_->[0]\t$_->[1]\t$_->[2]\n";

      [download]
      but get the same output 
      23        54        1
          54        2
11        65        3
