Hi,
Your first code snippet contains
my $node;
if ($node eq...

[download]
Is this a typo? $node will always eq undef in this case. Did you mean
my $node = param('node')

[download]
You could do it something like this: (untested code):
#!/usr/bin/perl
use CGI;

my $node = param('node');

my %lookup_table = (how => 'how_sub', foo => 'foo_sub');
if ($lookup_table{$node} ne '') {
    &{$lookup_table{$node}};
} else {
    print "Unknown sub called\n";
}

sub how_sub {}
sub foo_sub {}

[download]
The %lookup_table and if routine makes sure users cant choose any old sub to run,
just the ones you define in the lookup_table.
