This is a text function that appends the values of a single attribute across the episodes of a case together, with one value per line, and blank values skipped. It is mostly used in building reports for data mining applications. For example, suppose we had the following case fragment:
01 Jun 09 20 Jun 09 30 Jun 09 15 Oct 09 02 Nov 09 Destination Hanoi Florence New York Wollongong
Then the expression: list of Destination values would evaluate to:
Hanoi Florence New York Wollongong
