Avoiding user-input in sub calls.

[pekkhum]

Greetings, Perl Monks!
I have a program setup so that it chooses it's function(each one in a sub) based on user input. Naturally, it would be unwise to use this input directly in a call, so I devised a way to avoid it. My method works, but I think it obvious there is a better way to do it. Here is my current method, distilled:

#!perl -w

use strict;
use CGI qw/:Standard/;
CGI::header();


my $sub = CGI::param('type'); 
my $data = CGI::param('info');



if($sub eq 'first'){
    &one($data);
} elsif($sub eq 'second') {
    &two($data);
} else {
    &one($data);
}



sub one {
print "Sub one says: $_[0]";
}



sub two {
print "Sub two says: $_[0]";
}

Is there a better way to get this done? Any help is greatly appreciated!
