For example,
use strict;
use warnings;
$| = 1; # auto flush stdout
sub more { print "more()\n" }
sub fallover { print "fallover()\n" }
sub leave { print "Bye!\n"; exit; }
my %cmdhash = (
fun => \&more,
laugh => \&fallover,
exit => \&leave,
);
print "Welcome to johns fun house\n";
while (1) {
print " : ";
my $command=<>;
chomp $command;
if (my $func = $cmdhash{$command}) {
$func->();
} else {
print "I'm afraid I don't know how to \"$command\"\n";
}
}

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).
