I think this is close - I made a few changes but I am still only getting the 1st tier of keys when I really want all sublevels of keys. I would like $user_inputs to be an array ref which contains:

profiles, linewidth, single_dotnotes, legend, xvars, yvars

when I try pushing the return of the subfunction I get a bunch of wierd empty returns

function call

my $user_inputs = analyse_user_inputs($Settings);
print Dumper($user_inputs);

incoming hash/array combo

$Settings =
{
batchplot_output_filename => "gps3", 
plot_all_variables => 'off', 
# DEFAULT PLOTS & VALUES
default_values =>
[
{
profiles => [qw(prof1 prof2)],
linewidth => ["2"],
single_dotnotes => 'On',
legend => ["On"],
},
],
#BEGIN CUSTOM PLOTS
custom_plots =>
[
  [ 
    {
        yvars => 'LATDIIP',
        xvars => 'ELONGI',
    },
  ],  
]
}

subfunction

sub analyse_user_inputs {
    my $hashORarray_ref = shift @_;
    my @the_inputs;
        
if (ref $hashORarray_ref eq 'HASH') {
   foreach ( keys %{$hashORarray_ref} ){
#      print "$_ \n";
      push @the_inputs , $_ ;
      analyse_user_inputs($hashORarray_ref->{$_});
   }
}
if (ref $hashORarray_ref eq 'ARRAY') {
   for (my $i = 0; $i < scalar(@{$hashORarray_ref}); $i++) {
      analyse_user_inputs($hashORarray_ref->[$i]);
   }
}
   return(\@the_inputs);
