  1. DLITCBL

  2. CBLTDLI

  3. GOBACK

  4. PCB mask

  5. DBD

Show answer
Correct Option: A

AI Explanation

To answer this question, we need to understand the different elements involved in a COBOL IMS program.

Option A) DLITCBL - This option is incorrect. "DLITCBL" is not a valid COBOL IMS program statement.

Option B) CBLTDLI - This option is incorrect. "CBLTDLI" is not a valid COBOL IMS program statement.

Option C) GOBACK - This option is incorrect. "GOBACK" is a COBOL statement used to terminate a program, but it is not specific to IMS programs.

Option D) PCB mask - This option is incorrect. "PCB mask" refers to the Program Control Block (PCB) mask used in IMS programs, but it is not the first statement in a COBOL IMS program.

Option E) DBD - This option is incorrect. "DBD" refers to the Database Descriptor (DBD) used in IMS programs, but it is not the first statement in a COBOL IMS program.

The correct answer is A) DLITCBL. This option is correct because "DLITCBL" is the first statement in a COBOL IMS program. It is used to initiate the IMS environment and establish communication between the COBOL program and the IMS database.

What is the difference in coding between inserting segments into an existing database and loading a database?
technology databases

  1. The SSA must be qualified

  2. There is no difference.

  3. The key sequence of the data in loading

  4. There is no need for parentage in loading.

  5. The PCB processing options

Show answer
Correct Option: E

CALL ‘CBLTDLI’ USING ‘GU ‘ LS-PCB-MASK, WS-IO-AREA SEGMENTA*P SEGMENTC Based on above code what will be retrieved
technology databases

  1. Will retrieve segment C and parentage will be set at segment C

  2. Will retrieve segment C and parentage will be set at segment A

  3. Will retrieve segment A and parentage will be set at segment A

  4. Will retrieve segment A and parentage will be set at segment C

  5. Error out
