Not sure of the question.

If all arr[1-4] are the same size then
big_array = ndtooned( (/arr1,arr2,arr3,arr4/) )

-----

If all are different sizes ... *untested*

function combine(arr1[*]:string, arr2[*]:string \
,arr3[*]:string, arr4[*]:string )
local N1, N2, N3, N4, NN, nStrt, nLast, big
begin
N1 = dimsizes(arr1)
N2 = dimsizes(arr2)
N3 = dimsizes(arr3)
N4 = dimsizes(arr4)
NN = N1 + N2 + N3 + N4

big = new (NN,"string")
nStrt= 0
nLast= N1-1
big(nStrt:nLast) = arr1

nStrt = nLast+1
nLast = nStrt+N2-1
big(nStrt:nLast) = arr2

nStrt = nLast+1
nLast = nStrt+N3-1
big(nStrt:nLast) = arr3

nStrt = nLast+1
nLast = nStrt+N4-1
big(nStrt:nLast) = arr4

return(big)
end

big_array = combine(arr1, arr2, arr3, arr4)

Good Luck
