--data.txt--
apple, banana, strawberry
10, 20, 30, 40
red blue green yellow black
100 200 300
a b c d
-----------

data = []
num_arrays = rand(5)

File.open("data.txt") do |f|
  num_arrays.times do
    line = f.gets.strip()
    data << line.split("/,?\s*/")
  end
end

p data

--output:--
[["apple, banana, strawberry"], ["10, 20, 30, 40"], ["red blue green 
yellow black"]]

The names of the arrays are: data[0], data[1], data[2]
