in other operating environments as if those files were stored under z/OS. For further
information on CEDA, refer to Moving and Accessing SAS Files.
Utilizing Input/Output Features
Version 5 and 6 data sets generally need to be moved to SAS System 9 if you want to
take advantage of the I/O features introduced in SAS System 9 and Version 8. For
example, if you wanted to add integrity constraints to a Version 6 data set, you would
first have to move that data set to SAS System 9. For information on upgrading your
data sets, refer to Moving and Accessing SAS Files. For information on I/O features
introduced in SAS System 9, refer to the SAS Language Reference: Dictionary.
Reserved z/OS DDnames
In addition to the logical names shown in Table 1.4 on page 23, which have a special
meaning to SAS, you should be aware of the following reserved DDnames, which have a
special meaning to the operating environment:
JOBCAT
specifies a private catalog that the operating environment is to use instead of the
system catalog for the duration of the job (including jobs with more than one job
step).
JOBLIB
performs the same function as STEPLIB (described in Table 1.4 on page 23) except
that it can be used in a job that has more than one job step.
PROCLIB
specifies a private library of cataloged procedures to be searched before the system
library of cataloged procedures is searched. See your local SAS Support
Consultant for information about whether the PROCLIB DDname convention is
used at your facility.
SORTLIB
is used by some host sort utilities.
SORTMSG
is used by some host sort utilities to print messages.
SORTWKnn
specifies sort work data sets for the host sort utility. If allocated, this will be used
instead of the SASSWKnn data sets.
STEPCAT
specifies a private catalog that the operating environment is to use instead of the
system catalog for the current job step.
SYSABEND
in the event of an abnormal job termination, SYSABEND specifies a data set that
receives a medium-sized dump that consists of user-allocated storage and modules,
system storage related to current tasks and open files, and system and programs
related to the terminated job. See also SYSMDUMP and SYSUDUMP below.
SYSHELP
is used by TSO HELP libraries (not the SAS HELP facility).
