in thread Replace Array Elements with Hash Values

I tried to run the following and it replaces $string with %header rather than $string with $header[0], $header1, etc. Also, I thought my print command would add the newlines but it doesn't.

use Tk; use strict; use warnings; my $mw=new MainWindow; my @header = ("FHT_neg45","FHT_0","FHT_45","FHT_90","OHT_neg45","OHT_0 +","OHT_45","OHT_90"); my $button = $mw->Button(-text=>"temp", -command=> \&button)->pack(); MainLoop; sub button { #Read BJSFM_out.prn into an array @data my $filename="BJSFM_out.prn"; open my $fh, '<', $filename or die "Can't find $filename!"; my $string="1DO YOU WANT INSTRUCTIONS?"; my @data= map {chomp; $_ } <$fh>; my $n=0; for (@data) { if ($_ eq $string) { $data[$n] = $header[$n]; $n++; } } open my $write_fh, '>', 'temp.txt' or die $!; print $write_fh join " ",@data,"\n"; close $write_fh; }
