You can use the drop (_) operator, where n is a number to drop.
```
n_list
```
To remove from the end of the list:
```
-n_list neg[n]_list
```
If you want to remove nulls, you can do something like:
```
list except 0N
```
You can use the drop with each (‘) operator to remove the same numbers of items from each list of different length, i.e.
```
n_'(ls;ls2) -n_'(ls;ls2) neg[n]_'(ls;ls2)
```
Or removing nulls from them
```
(ls;ls2)except'0N
```
