Hallo people,
I cant get something done since a while. Its very basic stuff.. :(

I have the following hash for example :
hash = { $-a => "info", $F => "another info"}
and so on, you get the meaning..
Now i use Hash#each_pair so i get the value of the variables and the
info, but I would like also to get a simple string, containing
the name of the variable, so it should look like this :
$-a
info
false

$F
another info
nil

Do you want something like this:

hash={:name => "John Doe", :age => 23}

hash.each do |elem|
puts elem.join("\n")
end

That should work. You can also of course get the string as:

string=elem.join("\n")

Hope that helps.

But I cant get it done. Its probably very stupid question, but doesnt
matter what I try - i dont get the name of the key, i always get the
key itself returned... Can somebody help me?
Thanks in advance.
