Access your argument in the subroutine like this:
#!/usr/bin/perl -w
use strict;
sub do_this_cool_function {
my %args = (
-retire => "never",
-pizza => "cheese",
-payscale => 0,
-beer => "guiness",
@_, # argument pair list goes here
);
print "I wanna retire $args{-retire} if my pizza is $args{-pizza}.
+\n";
}
do_this_cool_function(-retire=>'early', -payscale=>-55.00, -pizza=>'co
+ld', -beer=>'none');
i don't get your error by the way. the only error your function call gives, is the following, because you didn't quote 'none':
Bareword "none" not allowed while "strict subs" in use at ./test.pl li
+ne 17.
Unquoted string "none" may clash with future reserved word at ./test.p
+l line 17.
Execution of ./test.pl aborted due to compilation errors.

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).
