I'd probably just put them all in the same hash:

require "yaml"

filename     = "data.yaml"
characters   = ["Molly", "Trade"]
saves        = {location: "Southeaster", hunger: 10, life: 76}
settings     = {display: "1360*960", render: "high", saves: "manual"}
program_data = {characters: characters, saves: saves, settings: settings}

# File.write may not be in some older versions of Ruby
File.write filename, YAML.dump(program_data)

loaded_data = YAML.load(File.read filename)

require 'pp'
pp loaded_data
# >> {:characters=>["Molly", "Trade"],
# >>  :saves=>{:location=>"Southeaster", :hunger=>10, :life=>76},
# >>  :settings=>{:display=>"1360*960", :render=>"high", :saves=>"manual"}}

Hi,<br>
<br>
I have a question. :-) I have already found a lot in the web but that<br>
does not really helped me. This far my code looks like this:<br>
<br>
<br>
to save:<br>
<br>
require &quot;yaml&quot;<br>
<br>
@characters =3D [&quot;Molly&quot;, &quot;Trade&quot;]<br>
@saves =3D {location: &quot;Southeaster&quot;,<br>
=A0 hunger: 10,<br>
=A0 life: 76<br>
=A0 }<br>
@settings =3D {display: &quot;1360*960&quot;,<br>
=A0 render: &quot;high&quot;,<br>
=A0 saves: &quot;manual&quot;<br>
=A0 }<br>
<br>
output =3D File.new(&quot;Saves.yaml&quot;, &quot;w&quot;) do |file|<br>
=A0 YAML.dump<br>
end<br>
output.write YAML.dump(@characters) # Wie sichert man mehrere<br>
Sachen??????<br>
output.close<br>
<br>
<br>
and to load:<br>
<br>
require &quot;yaml&quot;<br>
<br>
output =3D File.new(&quot;Saves.yaml&quot;, &quot;r&quot;)<br>
p YAML.load(output.read)<br>
output.close<br>
<br>
How can I save multiple array etc.?<br>
<br>
It works but I want to save more than one hash, I want to save e.g. all<br>
of them, but with that I can save just one or if I manage it to save all<br=
>
three I can just load the first one.<br>
So it would be nice if someone could help me. :-) Thanks<br>
<br>
Yours faithfully<br>
