To answer this question, we need to understand the purpose of the REGION keyword in a programming context.
The REGION keyword is used in programming languages, particularly in mainframe systems such as COBOL, to specify the amount of memory space required by a program step or job.
Option A) "Specifies the amount of space required by a step" - This option is correct. The REGION keyword can be used to specify the amount of memory space required by a particular program step.
Option B) "Specifies the amount of space required by a job" - This option is correct. The REGION keyword can also be used to specify the amount of memory space required by an entire job.
Option C) "Both of the above" - This option is correct. The REGION keyword can be used to specify the memory space required by a step and by a job.
Option D) "None of the above" - This option is incorrect. As explained above, the REGION keyword is used to specify the memory space required by a step or job.
Therefore, the correct answer is C) both of the above. This option correctly describes the purpose of the REGION keyword in programming languages.
