Re: Re: problem with hash keys

[june_bo]

Thanks for all the good advice.
I need to keep the order for cosmetic reasons; the user will expect to see the end results (a bunch of sets) in the same order he entered them.
I have to use hashes because I do (what I think are) wonderful and amazing things with them later in the program.

Thanks again to everyone.

Then you can additionally store for each hash the order in which its keys are in:

# ...
push @grammar_keys, $1 unless exists $grammar{$1};
$grammar{$1} = $2;
# ...
print "$k\n" for my $k (@grammar_keys);

(I've also taken the liberty of using lowercase variable names; you should probably use all-uppercase names only for special global variables).

Or you can use a module like Tie::IxHash, which implements hashes with ordered keys just like you want.
