SAS/GRAPH searches only librefs starting with GDEVICE0 through
GDEVICE9. The libraries must contain a catalog named DEVICES for
SAS/GRAPH to search for the device
entries for any driver. If you have personal device catalogs in more
than one SAS library, you must assign librefs in the sequence GDEVICE0,
GDEVICE1, GDEVICE2, and so on.
If the libref GDEVICE0
has been assigned to a SAS library,
SAS/GRAPH looks in that library
for a catalog named DEVICES. If the GDEVICE0.DEVICES catalog exists,
it is checked for the specified device entry. If the device entry
is not there,
SAS/GRAPH looks next for a library with the libref GDEVICE1
and for a catalog named DEVICES in that library. The search is repeated
for the sequence of librefs through GDEVICE9.
The search terminates
if either of the following are true:
-
Any of the GDEVICE libraries do
not contain a DEVICES catalog.
-
The librefs do not follow the numeric
sequence of GEVICE0, GDEVICE1, GDEVICE2, and so on, in that order.
If
SAS/GRAPH terminates the search for either reason,
or it does not find the specified device entry,
SAS/GRAPH searches the SASHELP.DEVICES catalog.
If the specified device entry is not found in the SASHELP.DEVICES
catalog, an error message is written to the log.
Note: As stated above, the search
for entries terminates if there is a break in the sequence. For example,
the catalog GDEVICE1.DEVICES is not checked if the libref GDEVICE0
is undefined or if GDEVICE0 does not contain a catalog named DEVICES.
