The SORTTIME parameter terminates the sort at the next breakpoint after n minutes of clock time have elapsed. (The sort may be restarted later.) The default is 1440 minutes (24 hours).
If this parameter is omitted or 1440 is specified, the sort will not terminate prematurely.
This parameter may be specified with operator communication at installation time. If operator communication is specified, the sort will be interrupted at the next breakpoint after the specified amount of time has elapsed and the operator will be asked whether to terminate the sort or continue until the next breakpoint.
