To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) CHCKPOINT DD statement - This option is incorrect because the CHCKPOINT DD statement is not typically used to store program checkpoints for use in a restart. The CHCKPOINT DD statement is used to define a checkpoint dataset for use with the IBM Debug Tool for z/OS.
Option B) SYSCHK DD statement - This option is correct because the SYSCHK DD statement is used to specify the dataset where program checkpoints can be stored for use in a restart. The program can write its checkpoints to this dataset, and then read them during a restart to resume execution from the last checkpoint.
Option C) CHKOUT DD statement - This option is incorrect because the CHKOUT DD statement is not typically used to store program checkpoints for use in a restart. The CHKOUT DD statement is used to define an output dataset for use with the IBM Debug Tool for z/OS.
Option D) CHECK or DD statement - This option is incorrect because there is no known statement called CHECK or DD statement that is used to store program checkpoints for use in a restart.
The correct answer is B) SYSCHK DD statement. This option is correct because it specifies the dataset where program checkpoints can be stored for use in a restart.
