In a nutshell, to get one value, call param() in scalar context. Call it in list
context to get
all values.
my $single_value = param( 'someval' ); # use this if you only have one value
my @multiple_values = param( 'somevals' ); # use this if you have multiple values
To get your snippet to work, try the following:
foreach my $name (param)
{
my @vals = param( $name );
print "$name - @vals\n";
}
