Hi,
I am a little confused with perl subroutines.
Can anybody explains the differences in ways to call subroutines for me.
sub Test {
my ($X,$Y) = @_;
return "Hello $X and $Y\n";
}
print "With &\n";
print &Test('name 1','name 2');
print "Without &\n";
print Test('name 1','name 2');
print "Without brackets\n";
print Test 'name 1','name 2';
what is the best practice to use, when and why?
Thanks in advance

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.
