See the reply to Fletch.

BTW, why introduce a variable, or even the named sub come to that?

$frame_2->Button(
    -text => 'Print', -width=>7,
    -command=>sub {print $scroll->Contents ()},
    )->pack(-side =>'bottom');

does what is required without the sub or variable, but doesn't show OP how to get the lines into an array and doesn't illustrate the technique required to use a named sub for the command handler.

It may well be that OP doesn't require instruction in such things and possibly no-one who comes after will benefit, but it wasn't much effort to illustrate those techniques and someone may learn from it.

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.
