#prototyped to explicitly state acceptable arguments
sub addstuff($$$);
...
#gives error if too few or too many arguments
#(or arguements of wrong type)
OTOH:
>perl -wMstrict -le
"my @ra = (99 .. 199);
;;
sub S ($$$) {
my $A = shift; my $B = shift; my $C = shift;
;;
return $A + $B + $C;
}
;;
print S 1, 2, @ra;
"

Maybe better read Far More than Everything You've Ever Wanted to Know about Prototypes in Perl -- by Tom Christiansen first, then generally avoid prototypes.

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.
