What are $hfile and $bfile? You don’t show them in your script. You show two arrays: @hfile and @bfile, but those are not the same as the scalar variables $hfile and $bfile. When asking other people for help, it is best to reduce your program down to the shortest version that illustrates your problem. People can help you fix that, and you can then apply the fix to your actual program. In this case, it is impossible to help you with the above stated problem, because the variable about which you are complaining do not exist in your program. If you actually mean @hfile and @bfile, you say that $copy is correct. Are the contents of the file named by $copy also correct? > The script begins: > > #!/usr/bin/perl > > use Tie::File; > use File::Copy 'copy'; > use File::Spec; > > > and further down, it has: > > # Tie it to an array > # > (my $copy = $htmfile) =~ s/(\.htm)\z/-Copy$1/i; > copy $htmfile, $copy; > tie my @hfile, 'Tie::File', $copy; > tie my @bfile, 'Tie::File', $recapfile; > > ## hfile is the array of the lines of htmfile > # > print "$copy \n"; > print "hfile: 1--$hfile-- \n"; > > $copy's value is correct. > > I'm on a Windows 7 machine.

No, because if you are getting any output at all from your Perl program, then the program has been found and executed by the operating system. > Happy to send the entire script to anyone who would like to see it.
