To answer this question, we need to understand the different types of programs in IMS (Information Management System).
A. DLI (Data Language Interface) - This is a type of IMS program that interacts with IMS databases using the DL/I (Data Language Interface) calls. It allows the program to read, write, update, and delete data in IMS databases. Therefore, an IMS Batch program can be run as a DLI.
B. BMP (Batch Message Processing) - This is another type of IMS program that processes messages in a batch environment. It can receive messages from IMS online programs or other batch programs, perform processing on the messages, and send responses back. Therefore, an IMS Batch program can be run as a BMP.
C. DBB (Database Batch) - This is a type of IMS program that performs batch database processing. It can read, update, and delete data in IMS databases without using the DL/I calls. Therefore, an IMS Batch program can be run as a DBB.
D. All of the above - This option is correct because an IMS Batch program can be run as a DLI, BMP, or DBB. All three options are valid ways to run an IMS Batch program.
Therefore, the correct answer is D) All of the above.
