Identifying Data Items to Mark as Unreferenced

To identify the data items that you want to mark as unreferenced, use the following combinations of the NAME, NAMEMASK, and CRITERIA keywords. Table 1 describes which of the three keywords to code in order to mark the desired data items as unreferenced.

Table 1. Identifying Data Items to Mark as Unreferenced
To Mark as Unreferenced:	Code:
A single data item	NAME
A changed data item	NAME CRITERIA=CHANGED
All data items	CRITERIA=ALL (the default)
Changed data items	CRITERIA=CHANGED
Data items whose names satisfy a character selection pattern.	NAME NAMEMASK
Changed data items whose names satisfy a character selection pattern.	NAME NAMEMASK CRITERIA=CHANGED

Coding both NAME and NAMEMASK defines a character selection pattern that the system uses to select names. For a general description of NAMEMASK and the character selection pattern, see Using Filters for Names on Requests.
