Example 10 SORTCNTL DD statement

//SORTCNTL DD  *
  OPTION MAINSIZE=8M

Note:

The OPTION statement keywords EFS, LIST, NOLIST, LISTX, NOLISTX, LOCALE, MSGPRT, MSGDDN, SMF, SORTDD, SORTIN, and SORTOUT are used only when they are passed by an extended parameter list or when in the DFSPARM data set. If they are specified on an OPTION statement read from the SYSIN or SORTCNTL data set, the keyword is recognized, but the parameters are ignored.
If your program invokes DFSORT more than once, you can direct DFSORT to read different versions of the SORTCNTL data set at each call. See the explanation of the SORTDD parameter in OPTION control statement.
If you use the DFSPARM DD statement instead of the SORTCNTL DD statement, you can specify both EXEC PARM options and DFSORT control statements in a single source data set that overrides all other sources. See DFSPARM DD statement. For override rules, see Specification/override of DFSORT options.
