in reply to Getting combinations from a number's digits

This solution is based on the combinational powers of glob()
my $txt = '123'; local $"=','; my @array = glob( "{@{[ split(//,$txt)]}}" x length($txt) ); print Dumper \@array ;

    That glob will also produce 111, 122, etc. Combinations without replacement are needed.

    um... I learned something. glob() is an actual module. I thought you were using it like we use blah or foo. Thanks, but does this use of glob create the 6 combinations for him? It seems the 6 combinations are hardcoded and he just want to store them somewhere for later use.
