If DFSORT was installed in a library not known to the system,
you must specify the DFSORT library in a JOBLIB or STEPLIB DD statement.
When you call Sort, certain sort data sets must not be open.
These are:
- SYSOUT
- A data set (normally the printer) on which messages from the
Sort program will be written.
Sort work data sets
-
SORTWK01–SORTWK32
-
Note:
If you specify more than 32 sort work data
sets, DFSORT will only use the first 32.
- ****WK01–****WK32
- From 1 to 32 working data sets used in the sorting process.
These must be direct access. For a discussion of space required
and number of data sets, see Determining storage needed for Sort.
**** represents the four characters that you can specify as the
data set prefix argument in calls to PLISRTx. This allows you to use data sets with prefixes other than
SORT. They must start with an alphabetic character and must not
be the names PEER, BALN, CRCX, OSCL, POLY, SYSC, LIST, or DIAG.
Input data set
- SORTIN
-
- ****IN
- The input data set used when PLISRTA and PLISRTC are called.
See ****WK01–****WK32 above
for a detailed description.
Output data set
- SORTOUT
-
- ****OUT
- The output data set used when PLISRTA and PLISRTB are called.
See ****WK01–****WK32 above
for a detailed description.
Checkpoint data set
- SORTCKPT
-
-
- Data set used to hold checkpoint data, if CKPT or CHKPT option
was used in the SORT statement argument and DFSORT's 16NCKPT=NO
installation option was specified. For information on this program
DD statement, see DFSORT Application Programming Guide.
- DFSPARM SORTCNTL
-
-
- Data set from which additional or changed control statements
can be read (optional). For additional information on this program
DD statement, see DFSORT Application Programming Guide.
See ****WK01–****WK32 above
for a detailed description.
