Use the "Array Subset" function.

Use "Array Subset" to get at that part of the array; use "Delete From Array" to remove that part and return a modified array.

"take out" can mean many things, so you should be a bit more clear.

1. Do you want to take the subset of elements 200-600 for futher processing. Here "array subset" is correct and you'll get a new array  of size=401 where element #0 is the old element #200, etc.
2. Do you want a new array of size=600 with elements 200-600 missing so the new element at index=200 would have the value of element #601 in the original data. Here "delete from array" would be correct.
3. Do you want to Keep the array the same size, but set elements 200-600 to zero or NaN? In this case "replace array subset" would be correct.

 Please clarify what you want. 🙂
