I don't know why you say the number of rows is hard coded. Why can't you just do this: foreach my $row (0 .. $lastRow)
{
}
But you might consider not storing it as a 2-dimensional array, but rather as a 22x80 character-long string. Then traversal becomes simply a matter of using substr and multiplying indexes (and it duplicates the behavior of wrapping that most terminals exhibit): my $screen = ' ' x ($rows * $columns);
foreach my $row (0 .. $rows-1)
{
my $rowText = substr($screen, $row*$columns, $columns);
}
# sets text, returns old text.
sub setTextAt
{
my $x = shift;
my $y = shift;
my $text = join('', @_);
substr($screen, $y * $columns + $x, length($text), $text);
}

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).
