Defining sort and merge data sets
To use DFSORT under z/OS®,
code DD statements in the runtime JCL to describe
the necessary data sets that are listed below.
About this task
- Sort or merge work
- Define a minimum of three data sets:
SORTWK01,SORTWK02,SORTWK03, . . .,SORTWKnn(where nn is 99 or less). These data sets cannot be in the z/OS UNIX file system. SYSOUT- Define for sort diagnostic messages, unless you change the data-set
name. (Change the name using either the
MSGDDNkeyword of theOPTIONcontrol statement in theSORT-CONTROLdata set, or using theSORT-MESSAGEspecial register.) SORTCKPT- Define if the sort or merge is to take checkpoints.
- Input and output
- Define input and output data sets, if any.
SORTLIB(DFSORT library)- Define the library that contains the sort modules, for example, SYS1.SORTLIB.
