How are records typically located and accessed in a relative file?
- By navigating through an index
- By specifying the record key
- By using the file position indicator
- Sequentially, based on record order
In a relative file, records are typically located and accessed by using the file position indicator. This indicator keeps track of the current position in the file, allowing for random access to records based on their relative record number.
COBOL allows you to define your own _____ in the Procedure Division to encapsulate specific functionality.
- Macros
- Paragraphs
- Segments
- Subroutines
In COBOL, the PERFORM statement is used to execute a section of code defined as a subroutine. This allows encapsulation of specific functionality within a procedure, improving code organization and maintainability.
The WRITE verb in COBOL can be used with the ________ clause to handle writing errors.
- ERROR
- EXCEPTION
- FILE STATUS
- INVALID KEY
In COBOL, the WRITE verb is used to write records to a file. The INVALID KEY clause is used to handle writing errors that may occur during the execution of the WRITE statement. It allows the program to take specific actions when a write operation encounters an error.
What is the purpose of arithmetic operations in COBOL programs?
- To control program flow
- To handle string manipulations
- To manage input/output operations
- To perform calculations and manipulate numeric data
Arithmetic operations in COBOL are used to perform calculations and manipulate numeric data. These operations include addition, subtraction, multiplication, and division, allowing programs to perform mathematical tasks.
In COBOL, what is the significance of the DEPENDING ON clause when used with the OCCURS clause?
- Define the initial value of an OCCURS clause
- Dynamically determine the number of occurrences at runtime based on a variable
- Set the upper limit for the number of occurrences in an OCCURS clause
- Specify the data type of the OCCURS clause
The DEPENDING ON clause in COBOL, when used with the OCCURS clause, allows you to dynamically determine the number of occurrences at runtime. This flexibility is valuable when the exact size of the array is unknown until the program is executed.
The _____ clause is used to declare the initial value of a COBOL constant.
- ASSIGN
- DEFAULT
- INITIAL
- VALUE
In COBOL, the VALUE clause is used to declare the initial value of a constant. It allows you to assign a value to a data item at the time of its declaration.
The ______ condition handler in COBOL allows you to define custom error-handling logic based on specific conditions.
- CONDITION-CONTROL
- CONDITION-HANDLER
- HANDLER-CONDITION
- HANDLING-CONDITION
The CONDITION-HANDLER in COBOL enables the programmer to define custom error-handling logic based on specific conditions. It provides a way to handle errors or exceptional situations in a tailored manner.
A group item in COBOL can contain multiple elementary items and is defined using the _________ keyword.
- FILLER
- GROUP
- OCCURS
- REDEFINES
In COBOL, a group item is defined using the GROUP keyword. It allows for the grouping of multiple elementary items under a common name for organizational and hierarchical structuring of data.
What role does the "SORT" operation play in optimizing file handling performance in COBOL?
- It arranges data in ascending order for readability
- It helps in sorting large files for efficient processing
- It is used to concatenate multiple files
- It optimizes file storage for faster retrieval
The "SORT" operation in COBOL is used to arrange data in a specified order, facilitating efficient processing of large files by enabling easier retrieval based on the sorted key.
In COBOL, which operator is used for addition?
- * (Multiply)
- + (Plus)
- - (Minus)
- / (Divide)
The addition operation in COBOL is represented by the plus (+) operator. It is used to add two or more numeric values in COBOL programs.
