Hello,

Here is the short form:
Quote:
Checkpoint/Restart is a facility of the operating system that allows information about an application to be recorded so that same application can be restarted after abnormal termination or after some portion of the application has been completed.


If you'd like more info, it is available in the manual linked to from this forum (that's where the above came from).

DFSORT has a checkpoint facility, but it is not recommended because it prevents DFSORT's most efficient technique (Blockset) from being used.
For more information, see:
