SYSCHK DD statement

Purpose: Use the SYSCHK DD statement to define a checkpoint data set that the system is to write during execution of a processing program. Use this statement again when the step is restarted from a checkpoint written in the data set.

Note: If restart is to begin at a step, as indicated by the RD parameter on the EXEC statement, do not use a SYSCHK DD statement.
