title: nested array of literals [[1,2,3]] in batch job
body: <p>what happens when you want to process an nested array of literals for
  example [[1,2,3]] by a batch job in which there are 2 batch steps within
  each a variable and a logger. In the first variable there is an dw with
  "payload ++ one" and in the second batch step a variable with dw
  "payload ++ two" and after that variable a logger ? Will that nested array processed or will that give an error? and if that is processed
  what is the result?</p>
