Subject: Re: Printing Hash Keys
Thanks RaFaL,
print join "\t", sort keys %params;
works excellently.
What if I don't want to sort them (display the keys in the same order they
were entered)?
Let's say the hash was:
%params = qw(
dirt 4
sand 5
land 2
air 5
wind 9
breath 1
);
A sorted hash would come out as:
air breath dirt land sand wind
5 1 4 2 5 9
how can I make it come out the same order I entered them?
ie.
dirt sand land air wind breath
4 5 2 5 9 1
Cheers,
-Shannon
