I used you code for my own problem and it worked fine in the beginning but the moment I add another array to @groups the order of the arrays changes intern.I have little experiences with subs so I don't know how to change the code to make sure the order stays the same?

my @groups=(
[qw( yes no 0 )],
[qw( yes all 0 )],
[qw( all stop 0 )],
[qw( 1 0 )],
[qw( 1 0 )],    );        
my @names=('rscode','nonsyn','aac','splice','var');
my $fixed_size=scalar(@names);    
my ($combo,$count)= create_combo($fixed_size,\@groups);    

sub create_combo 
{
    my @array;
    my $count=0;
    my $fixed_size= $_[0];
    my $groups=$_[1];
    for my $fixed_size_groups ( combine( $fixed_size, @{$groups} ) ) 
    {    Algorithm::Loops::NestedLoops $fixed_size_groups, 
        sub {
            push @array,@_;    
            print "@_\n";
            $count++;
           };
  return (\@array,$count);
  }

    
}

It gives as result

1 all 1 yes yes
1 all 1 yes all
1 all 1 yes 0
....

which are the right combinations but not the right order of the elements! Any help is much appreciated.
