Many
SAS/GRAPH procedures use and create SAS data
sets. SAS data sets are files stored in SAS libraries and can be either
temporary or permanent.
When you create a SAS
data set, it is stored automatically in the WORK library. Unless you
specify a different library, the WORK library serves as a temporary
holding place for all the data sets you access and create. The WORK
library exists for the duration of a SAS session. By default, the
WORK library and all the data sets stored in it will be removed after
the SAS session ends.
You can also create
permanent SAS libraries that can be saved in a specified location
on your computer. Permanent libraries are not deleted when the SAS
session terminates and are available for processing in subsequent
SAS sessions.
