To answer this question, let's go through each option:
A. When TIME is added to a JOB statement, the entire job run time is limited to that amount.
This statement is true. When the TIME parameter is added to a JOB statement, it sets a limit on the total run time for the job. If the job exceeds the specified time limit, it will be terminated.
B. When REGION=0 is coded, the job will not execute due to the fact that no working storage.
This statement is false. When REGION=0 is coded on the JOB statement, it sets the maximum amount of virtual storage that the job can use to zero. This means that the job will not be able to allocate any virtual storage and may fail due to storage constraints. However, it does not necessarily mean that the job will not execute. It will depend on the specific program being executed and how it handles storage allocation failures.
C. The COND parameter on JOB level will place the same condition on every EXEC statement.
This statement is true. The COND parameter on the JOB level specifies a condition that is applied to every subsequent EXEC statement within the job. If the condition is not met, the EXEC statement will not be executed.
D. TYPRUN=SCAN means that the entire JCL script will be checked for syntax and value.
This statement is false. TYPRUN=SCAN is used to perform a syntax and value check on each job step individually, not on the entire JCL script. It allows for early detection of syntax errors and invalid values before the job is actually executed.
Based on the explanations above, the correct answers are A and C.
