I am trying to parse a text file with the following code: 
sub parse    {



    open(CLOG, "<$flatfile") || die ("Cannot open $flatfile for readin
+g... $!\n");
          
    foreach $tracknumber (<CLOG>)    {

        $tracknumber =~ s/\<Num_0\>/0/g;
        $tracknumber =~ s/\<Num_1\>/1/g;
        $tracknumber =~ s/\<Num_2\>/2/g;
        $tracknumber =~ s/\<Num_3\>/3/g;
        $tracknumber =~ s/\<Num_4\>/4/g;
        $tracknumber =~ s/\<Num_5\>/5/g;
        $tracknumber =~ s/\<Num_6\>/6/g;
        $tracknumber =~ s/\<Num_7\>/7/g;
        $tracknumber =~ s/\<Num_8\>/8/g;
        $tracknumber =~ s/\<Num_9\>/9/g;
        $tracknumber =~ s/\<Num_\.\>/\./g;
        $tracknumber =~ s/\<Num_\-\>/\-/g;
        $tracknumber =~ s/\<Num_\/\>/\//g;
        $tracknumber =~ s/\<Tab\>/\t/g;
        $tracknumber =~ s/\<Tab//g;
        $tracknumber =~ s/\<Up\>//g;
        $tracknumber =~ s/\<Down\>//g;
        $tracknumber =~ s/\<Alt\>//g;
        $tracknumber =~ s/\<Ctrl\>//g;
        $tracknumber =~ s/\<PgDwn\>//g;
        $tracknumber =~ s/\<PgUp\>//g;
        $tracknumber =~ s/\xA0/ /g;
        $tracknumber =~ s/\xA1//g;
        $tracknumber =~ s/\xA2//g;
        $tracknumber =~ s/\xA4//g;
        $tracknumber =~ s/\x0D/\n/g;
        $tracknumber =~ s/\x0A/\n/g;
        $tracknumber =~ s/\<Num_//g;
        $tracknumber =~ s/\<Num//g;
        $tracknumber =~ s/\<Nu//g;
        $tracknumber =~ s/\<Numpad_3\>/\n/g;
        $tracknumber =~ s/pad_3\>/\n/g;
        open(OUTPUT, "+>>$output") || die ("Cannot open output file$!\
+n");
            print OUTPUT "$tracknumber";
        close OUTPUT;
    }

    close CLOG;

}

As you can see, I am doing quite a few search and replace functions, but the problem I am having is this: the text file from which I'm reading also contains statements such as <Left>, <Right>, and <Del> (it is the output from a keylogger), and I need to reflect the cursor movement that these keys cause in the final output file (I am parsing the output file because it the text is quite unreadable straight out of the logger.) Also, does anyone have an idea about how I might be able to parse the whole file in one big chunk instead of line-by-line (as "foreach" does)? The line-by-line business really messes up the final parsed output. Thanks guys/gals!
