Hi all,
Running the following program outputs:
Perl 5.008004
undef
undef
undef
2
but it should output:
Perl 5.008004
undef
undef
undef
undef
The code goes as follows :-
#!/usr/bin/perl -w
print "Perl $]\n";
sub show {
my ($val) = @_;
if (! defined $val) {
print "undef\n";
} else {
print "$val\n";
}
}
sub sb {
my $v1;
$v1 = -1 if 0;
my $v2 = -2 if 0;
show $v1;
show $v2;
$v1 = 1;
$v2 = 2;
}
sb;
sb;

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.
