Figure 1. RESTART Format
This parameter specifies the point at which restart is to occur.
LAST, the default value, requests that the sort start at the most recent breakpoint.
NO specifies that the SORTBKPT data set is to be cleared so that it can be used for a new job. (Be sure to specify NO only when the SORTBKPT data set is empty or should be destroyed.)
To restart at a particular breakpoint, code its id number. The breakpoint id number is provided by message WER350I.
