- STEPCHKPT
-
enables checkpoint mode, which specifies to record checkpoint-restart
data.
- NOSTEPCHKPT
-
disables checkpoint mode, which specifies not to record
checkpoint-restart data. This is the default.
Using the STEPCHKPT system option puts SAS in checkpoint
mode for SAS programs that run in batch. Each time a DATA step or PROC step
executes, SAS records data in a checkpoint-restart library. If a program terminates
without completing, the program can be resubmitted, beginning with the step
that was executing when the program terminated.
To ensure that the checkpoint-restart data is accurate, when you specify
the STEPCHKPT option, also specify the ERRORCHECK STRICT option and set the
ERRORABEND option so that SAS terminates for most errors.
Checkpoint mode is not valid for batch programs that contain
the DM statement, which submits commands to SAS. If checkpoint mode is enabled
and SAS encounters a DM statement, checkpoint mode is disabled and the checkpoint
catalog entry is deleted.
