What sort of insight are you seeking? Specific questions about lines
of code would be more helpful. (Followup your original post if
you want to do that.)

OK...I dug up the subroutine called param in CGI.pm. Anyone care to give me a little insight into it?

sub param {
my($self,@p) = self_or_default(@_);
return $self->all_parameters unless @p;
my($name,$value,@other);

# For compatibility between old calling style and use_named_parameters() style,
# we have to special case for a single parameter present.
if (@p > 1) {
($name,$value,@other) = rearrange([NAME,[DEFAULT,VALUE,VALUES]],@p);
my(@values);

if (substr($p[0],0,1) eq '-') {
@values = defined($value) ? (ref($value) && ref($value) eq 'ARRAY' ? @{$value} : $value) : ();
} else {
foreach ($value,@other) {
push(@values,$_) if defined($_);
}
}
# If values is provided, then we set it.
if (@values) {
$self->add_parameter($name);
$self->{$name}=[@values];
}
} else {
$name = $p[0];
}

return unless defined($name) && $self->{$name};
return wantarray ? @{$self->{$name}} : $self->{$name}->[0];
}

ahh well...maybe you are right and I am asking other people to do work
for me....sorry about that

to explain the post better, though, people here have told me many
times I can't live without CGI.pm ....so I would like to know exactly
what that module does that I can't understand.

anyway, you are right...I really should read the code myself for a
week or a month and come back later with specific questions instead of
asking for a general walkthrough right off the bat
