Hi Perlian,
How come my code below doesn't update the original
hash (%line)?
my %line = ('A' =>1,
'B' =>1,
'C' =>1);
my @tojoin = qw (W X Y Z);
foreach my $line ( keys %line )
{
print "$line\n";
foreach my $tojoin ( @tojoin )
{
my $nstr = $line.$tojoin;
$line{$nstr} = 1;
}
last if ($line eq 'AYW');
}
Such that finally the %line will give:
A => 1,
B => 1,
C => 1,
AW => 1,
.... until
AYW => 1

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).

or How to display code and escape characters
are good places to start.
