Re: Misprinting combinations / iterator

I haven't used this particular module, but from looking at the documentation.. $combination is a reference to an array (an arrayref) - that needs to be deferenced. print "@$combination\n"; looks like what you need.

The examples in the module's docs weren't completely explanatory - I can see how this was confusing! There is a "core" module (meaning that is pre-installed and exists on all Perl installations), Data::Dumper. It can print a representation of any Perl data structure - WOW! You need to give it a reference to the structure. This is fantastic debugging tool. There is no equivalent in 'C' or 'Java' of which I am aware. `use Data::Dumper; # in your loop put... print Dumper \$combination;` [download]	[reply] [d/l]
