Second Mock Test Cbe11mf004

The statement is true because the OPEN statement is used to establish a connection between a program and a file, allowing the program to access and manipulate the file's contents. Without executing the OPEN statement, the program would not be able to read from or write to the file. Therefore, it is necessary for the processing of a file to begin with the execution of an OPEN statement.

The "ORGANIZATION IS INDEXED" clause is used in COBOL programming language to specify that a file is an indexed file. This means that the records in the file are organized and can be accessed using an index key. Therefore, the given statement is true.

The correct answer is SET. This verb is used to set, increase, or decrease the value of the indexes. It allows the manipulation of index values in order to control the flow of a program or to access specific elements within a data structure.

The phrase "DELIMITED BY" sets the limits of the string. This means that it defines the boundaries or separators within the string, indicating where one part of the string ends and another begins. It is used to specify how the string should be divided or segmented into smaller parts.

This statement is true because in programming, a called program can invoke or call other programs or functions to perform specific tasks. However, it is important to avoid calling the calling program to prevent creating an infinite loop or causing unexpected behavior. This practice helps maintain the flow and organization of the program, ensuring that each program or function is responsible for its own specific task and does not interfere with the calling program.

The statement is true because the INITIALIZE verb in the PROCEDURE DIVISION of a COBOL program is used to set all the values of a group of variables to their initial values. This is a convenient alternative to using the MOVE verb to individually assign initial values to each variable. The INITIALIZE verb simplifies the code and makes it more readable by initializing multiple variables at once.

The correct answer is "TIMES" because when using the "PERFORM" statement with the "TIMES" phrase, the specified block of code will execute the number of times specified by the value in the identifier or integer. This allows for a specific number of iterations to be performed, providing control over the repetition of the code.

By using the REPLACING option with the INITIALIZE verb, we can set alphanumeric fields to values other than spaces and numeric fields to values other than zeroes. This option allows us to replace the initial values of the fields with specific values, providing more flexibility in initializing variables.

The correct answer is input file, output file, and the work file. This is because the SORT verb in this context requires the naming of these three files in order to perform the sorting operation. The input file is the file that contains the data to be sorted, the output file is where the sorted data will be written to, and the work file is used for temporary storage during the sorting process.

When "at END of file" occurs, it means that the program has reached the end of the file it is reading. In this case, the FILE STATUS would be set to 10. This status indicates that the program has successfully reached the end of the file without any errors.

The given correct answer is "WITH POINTER". This suggests that for the mentioned clause, it is possible to start the transfer of characters from some other location using a pointer. The other options, "PICTURE" and "Neither WITH POINTER nor PICTURE", are not applicable in this case.

The term "index" represents the displacement value of the entry from the beginning of a table. In other words, it indicates the position or location of a particular entry within the table. This is commonly used in databases and data structures to efficiently retrieve and manipulate data. The other options, superscript, subscript, and all the above, do not accurately describe the displacement value of an entry in a table. Therefore, the correct answer is "index".

The correct answer is "EXIT" because when this verb is executed, it indicates that the program should terminate and no further action should be taken. It is commonly used to exit loops or terminate the program completely.

The FILE STATUS field in the data division should be defined as a two character alphanumeric field. This means that it can contain both letters and numbers, allowing for a wider range of possible values. Using an alphanumeric field for the FILE STATUS allows for more flexibility in representing different statuses or codes related to the file.

Indexes can be manipulated by using the SET command to modify their values, the SEARCH command to find specific indexes, and the PERFORM command to execute operations on indexes. Therefore, all of the above options are correct as they can be used to manipulate indexes.

The WRITE statement is used to write data to a file. However, when a file is opened in the I-O (input-output) mode, it allows both reading and writing operations on the file. In this mode, the WRITE statement cannot be used because it is not allowed to write data to the file. Therefore, the statement "The WRITE statement cannot be used for files opened in the I-O mode" is true.

The given code snippet will execute P2 0 times. This is because the loop condition states that P2 should be executed "UNTIL i

By using the "THRU" option with PERFORM, we can execute a series of procedures in a sequence. Similarly, by using the "THROUGH" option with PERFORM, we can also execute a series of procedures in a sequence. Therefore, the correct answer is "Both a and c" as both the "THRU" and "THROUGH" options allow for executing a series of procedures in a sequence.

Indexing allows for direct access to specific data within a table. By using an index, you can quickly locate and retrieve the desired information without having to scan the entire table. This improves the efficiency and speed of data retrieval operations. Therefore, the correct answer is "Index".

The correct answer is "set". The "set" operation is used to transform and move data from one index item to another or from a subscript to another or from a subscript to the corresponding item. This operation allows for the reassignment or relocation of data within an index or subscript.
