OUTPUTLEN can be used to setup the width of the column (if you don’t use automatic column width optimization). When automatically created, usually it have the value of the maximum field width, but when you create it manually you can setup it to whatever value you want.

My experience shows that it is useful when you have a field that have maximum length of few characters but the description of the column is long. In such case with OUTPUTLEN you can decide if you want to adjust the column width to the width of the value or to the width of column description.
Below some examples of the different settings of the OUTPUTLEN for the field CITYFROM.
