( #3333=superdoc: print w/ replies, xml ) Need Help??
      Could somebody help me do this on a faster way? Thanks!

Faster? <shrug!> dunno, but pull up a chair. Here are the two input files..

$ cat file1.txt 1 2 3 4 5 $ cat file2.txt 5 4 3 2 1
and here's some code:
#!/usr/bin/perl -w use strict; use Tie::File; my ($file1,$file2,$fileout) = @ARGV; tie my @ry1,"Tie::File",$file1 or die "$file1:$!"; tie my @ry2,"Tie::File",$file2 or die "$file2:$!"; tie my @out,"Tie::File",$fileout or die "$fileout:$!"; @out=(@ry1,@ry2); untie @out; untie @ry2; untie @ry1;
which gives you this as an output:
$ cat out.txt 1 2 3 4 5 5 4 3 2 1
