Hi Monks,
The perl program below should print 3 identical lines,
#! /usr/perl -l
sub f1 {
my ($f) = @_;
my @z = ("$f");
for my $d (@z) {return $d}
}
sub f2 {
my ($f) = @_;
for my $d ("$f") {return $d}
}
sub f3 {
for my $d (@_) {return $d}
}
print map {f1($_)} qw(x y z);
print map {f2($_)} qw(x y z);
print map {f3($_)} qw(x y z);
Output:
xyz
zzz
xyz
why does it happen. I run this program in unix ksh.

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.
