record-list is a list of record keys, or an asterisk (*) to signify all records.
n is the field number in each record, from which the list is to be created. If n is not specified, all the fields in the source records will be used to generate the list elements.

Also, FORM-LIST creates a list from all the attributes of a single record, QSELECT can create a list from multiple records, and you can specify that each record is only to contribute one field.
