Using our within a block makes the variable a package global only within that block. To make the global valid throughout the entire file, simple put our $text at the top. You're also re-declaring $text inside your while loop each time and then matching it, which doesn't make sense, and should result in a "Use of uninitialized value in substitution" warning.

However, it's good practice to avoid global variables when possible. Instead, you can do something like this:

use strict; use warnings; use Data::Dumper; sub load_file { my $file = shift; my $text; { local $/; open my $fh, $file or die "Can't open $file $!"; $text = <$fh>; } return $text; } my $text = load_file( '/home/greyfox/data/TBLLOTUSNOTESPYRAMID.txt' );

Then, you can pass $text as a parameter to a subroutine that processes the second file, for example.

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
