ruby code:
------------------
myhash = Hash.new{|h, k| h[k] = [nil] * 3}

myhash['customercode'][0]='Firstname'
myhash['customercode'][1]='M.I'
myhash['customercode'][2]='Lastname'

myhash.each do |k,v|
 myhash[k].each do |elm|
   puts "#{k} -> #{elm}"
 end
end

output:
-------------------
customercode -> Firstname
customercode -> M.I
customercode -> Lastname

does that help?
