Prototyping? Am I missing something here? This seems to work:
sub mylcfirst {
my $x;
if (@_) { $x = join "", @_ }
else { $x = $_ }
$x =~ s/(.)/\l$1/;
return $x;
}
sub myuc {
my $x;
if (@_) { $x = join "", @_ }
else { $x = $_ }
$x =~ s/(.*)/\U$1/;
return $x;
}
sub myreverse {
my $x;
if (@_) { $x = join "", @_ }
else { $x = $_ }
$x = reverse $x;
return $x;
}
### sample1
$_ = 'lrep esu';
$str = myreverse mylcfirst myuc;
print $str."\n";
### sample2
$_ = 'lrep esu';
$str = mylcfirst myreverse myuc;
print $str."\n";
Sure, the code is a little clunky. And it doesn't take reverse in list context into account, but the idea is there. What part of this isn't what you are expecting?

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).
