Initializing and Configuring SAS Software

Reserved z/OS ddnames

In addition to the logical names shown in SAS Software Files, 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 SAS Software Files) 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 on-site SAS support personnel 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 ddname is 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).
SYSLIB: is used by some IBM system utility programs.
SYSMDUMP: in the event of an abnormal job termination, SYSMDUMP specifies a data set that receives a system dump in IPCS format. The contents of the dump are determined by z/OS installation options, although SYSMDUMP generally includes all user-allocated storage, all system-allocated storage used to control job execution, and all program modules (system modules and user programs) that were in use at the time the dump was taken.
SYSOUT: is used by some utility programs to identify an output data set.
SYSPRINT: is used by some utility programs to identify a data set for listings and messages that might be sent to the printer.
SYSUADS: is used by some TSO commands that might be invoked under SAS software.
SYSUDUMP: in the event of an abnormal job termination, SYSUDUMP specifies a data set that receives a "short" system dump that consists of user-allocated storage and modules and system storage related to current tasks and open files. See also SYSABEND and SYSMDUMP above.
SYSnnnnn: is reserved for internal use (for dynamic allocation) by the operating environment.
