GDG New Generation created is specified with relative number of
- A.
+2
- B.
-1
- C.
+1
- D.
0
Correct Answer
C. +1Explanation
The correct answer is +1 because it is the only option that follows the pattern of the given sequence. Each number in the sequence is either increasing or decreasing by a certain amount. The first number increases by 2, the second number decreases by 1, and the third number increases by 1. Therefore, the next number should increase by 1, making +1 the correct answer.Rate this question:

The step will always be executed within or not a preceding step abnormally terminates when coded as ______
- A.
COND=EVEN
- B.
COND=ODD
- C.
COND=ONLY
- D.
None
Correct Answer
A. COND=EVENExplanation
When the step is coded as COND=EVEN, it means that the step will only be executed if the preceding step abnormally terminates and the return code is an even number. In other words, if the preceding step terminates normally or abnormally with an odd return code, the step will not be executed. Therefore, this coding ensures that the step will always be executed within the condition specified.Rate this question:

- A.
IDSORT
- B.
IEBGENER
- C.
IEFBR14
- D.
IDCAMS utility
- E.
All
Correct Answer

If two jobs have same priority value & the same jobclass value then they will be executed as they are submitted
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
If two jobs have the same priority value and the same job class value, it means that they have equal importance and belong to the same category. In this case, the jobs will be executed in the order they are submitted, as there is no other criteria to differentiate between them. Therefore, the statement "If two jobs have the same priority value & the same job class value then they will be executed as they are submitted" is true.Rate this question:

In GDG same JCL code can be used to process every cycle with a single Application .
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In GDG (Generation Data Group), the same JCL (Job Control Language) code can be used to process every cycle with a single application. This is because GDG allows for the creation of multiple versions of a dataset, each with a unique generation number. By specifying the GDG base name in the JCL code, the job can automatically process the latest version of the dataset without needing to modify the code for each cycle. Therefore, the statement "True" is correct.Rate this question:

For variable length, unblocked records logical recordlength equals to Blocksize
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
For variable length, unblocked records, the logical record length does not have to equal the block size. In fact, in this case, each record can have a different length and is not required to fill up an entire block. Therefore, the statement is false.Rate this question:

If both JOBLIB & STEPLIB statements are coded then STEPLIB specification will override JOBLIB specification
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When both JOBLIB and STEPLIB statements are coded, the STEPLIB specification will override the JOBLIB specification. This means that the system will prioritize the libraries specified in the STEPLIB statement over the libraries specified in the JOBLIB statement when searching for programs or datasets. Therefore, the answer is true.Rate this question:

When we specifies variable for RecFM parameter LRECL value is largest Record in the file plus 5 bytes
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because when specifying the variable for the RecFM parameter LRECL value, it should be the largest record in the file plus 1 byte, not 5 bytes.Rate this question:

___ specifies the largest amount of main memory for any job step within the job.
- A.
Notify
- B.
Region
- C.
Typrun
- D.
None of the above
Correct Answer
B. RegionExplanation
The correct answer is "region". In a job, the "region" specifies the largest amount of main memory that can be used by any job step within that job. This setting helps allocate memory resources efficiently and ensures that each job step has enough memory to execute successfully. By setting a maximum region size, the system can prevent a job step from using excessive memory and potentially causing performance issues or system crashes.Rate this question:

JCL statements are coded in _____ records.
- A.
80 bytes
- B.
82 bytes
- C.
72 bytes
- D.
84 bytes
Correct Answer
A. 80 bytesExplanation
JCL statements are coded in 80 bytes records. This means that each JCL statement can occupy a maximum of 80 bytes in the JCL file. This record length allows for efficient storage and processing of JCL statements in mainframe systems.Rate this question:

- A.
142
- B.
80
- C.
20
- D.
152
- E.
255
Correct Answer
A. 142Explanation
The maximum size of accounting information is 142. This means that the amount of data that can be stored or transmitted for accounting purposes is limited to 142 units of measurement. This could refer to the number of characters, bytes, or any other unit of measurement used to quantify the size of the information.Rate this question:

REGION = ___ means all available spaces allocated to a job.
- A.
0K
- B.
0M
- C.
0K or 0M
- D.
None of these
Correct Answer
C. 0K or 0MExplanation
The answer "0K or 0M" suggests that the REGION parameter can be set to either 0K or 0M, indicating that the job does not require any additional memory allocation beyond what is already available. This means that the job will utilize the default memory space allocated to it by the system, without any additional memory being allocated specifically for that job.Rate this question:

Concatenation has meaning only for sequential processing
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Concatenation refers to the act of combining two or more strings together. In the context of sequential processing, concatenation is meaningful because it allows for the merging of strings in a specific order. However, in non-sequential processing, where the order of operations is not predetermined, concatenation may not have a clear or meaningful outcome. Therefore, the statement that "concatenation has meaning only for sequential processing" is true.Rate this question:

Alternate indexes (AIXs) allows logical records of a KSDS or of an ESDS to be accessed sequentially and directly by more than one key field.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Alternate indexes (AIXs) are a feature in mainframe databases that allow multiple key fields to be used for sequential and direct access to logical records in a Key Sequenced Data Set (KSDS) or an Entry Sequenced Data Set (ESDS). This means that different key fields can be used to access the same records, providing more flexibility in searching and retrieving data. Therefore, the given answer "True" is correct.Rate this question:
