We have the following function in the Prelude:

splitAt :: Int -> [a] -> ([a], [a])

For example,

Prelude> splitAt 3 [1..12] ([1,2,3],[4,5,6,7,8,9,10,11,12])

So you can write the following function (you can choose another name):

separate :: Int -> [a] -> [[a]]

For example,

Prelude> separate 3 [1..12] [[1,2,3],[4,5,6],[7,8,9],[10,11,12]]

This is the splitEvery function of package split; you can find this with Hayoo, using the word "split". Regards, Henk-Jan van Tuyl -- http://Van.Tuyl.eu/ http://members.chello.nl/hjgtuyl/tourdemonad.html --
