Indicates to execute the DATA step or PROC step that
immediately follows without considering the checkpoint-restart data.
The CHECKPOINT EXECUTE_ALWAYS
statement indicates to SAS that the DATA
step or PROC step that immediately follows is to be executed without considering
the checkpoint data.
If checkpoint-restart mode is enabled and a batch program terminates
without completing, the program can be rerun beginning with the DATA step
or PROC step that was executing when it terminated. DATA or PROC steps that
completed before the batch program terminated are not reexecuted. If a DATA
step or a PROC step must be reexecuted, you can add the CHECKPOINT EXECUTE_ALWAYS
statement before the step. Using the CHECKPOINT EXECUTE_ALWAYS statement ensures
that SAS always executes the step without regard to the checkpoint-restart
