A length which is larger than the argument length causes [[Fill element|fills]] to be inserted. The alignment remains the same: if two different positive arguments are used to take from an array, the one which is closer to zero gives a [[prefix]] of the other result. If they are both negative, it is a [[suffix]] instead. | A length which is larger than the argument length causes [[Fill element|fills]] to be inserted.

In languages with the SHARP APL extension, the left argument can be shortened. This causes leading axes of the right argument to be modified while trailing axes are ignored. | In languages with the SHARP APL extension, the left argument can be shortened.
