In addition, there are
now three predefined librefs for libraries that contain map data sets.
Those librefs are as follows:
Use the MAPS libref
in your applications.
CAUTION:
Do not
use the MAPSGFK or MAPSSAS librefs as they are reserved for future
SAS development.
Using these librefs
could cause unexpected results when run with your existing code. When
these libraries are no longer preproduction, the usage information
will be available.
