Definition of a DICTIONARY Table
A DICTIONARY table is a read-only SAS view that contains information about SAS libraries, SAS data sets, SAS macros, and external files that are in use or available in the current SAS session. A DICTIONARY table also contains the settings for SAS system options that are currently in effect.
When you access a DICTIONARY table, SAS determines the current state of the SAS session and returns the desired information accordingly. This process is performed each time a DICTIONARY table is accessed, so that you always have current information.
DICTIONARY tables can be accessed by a SAS program by using either of these methods:
-
run a PROC SQL query against the table, using the DICTIONARY libref
-
use any SAS procedure or the DATA step, referring to the PROC SQL view of the table in the SASHELP library.
For more information on DICTIONARY tables, including a list of available DICTIONARY tables and their associated SASHELP views, see SAS 9.2 SQL Procedure User's Guide.
