thanks.. (as mentionned in a second post I found a solution)
I try to rewrite these 6 lines  into  one line :

months = []
1.step(12, 1) do |i|
l = Date::MONTHNAMES[i]
m = i.to_s
months << [ l, m ]
end

which produces :
[["January", "1"], ["February", "2"], ["March", "3"], ["April", "4"],
["May", "5"], ["June", "6"], ["July", "7"], ["August", "8"],
["September", "9"], ["October", "10"], ["November", "11"], ["December",
"12"]]

I need the array months as a parameter for  'options_to_select()'
(Rails function)
