When implementing exception handling in COBOL, the _______ statement is used to propagate an exception to higher-level routines.
- PROPAGATE
- RAISE
- SIGNAL
- THROW
The PROPAGATE statement in COBOL is used to propagate an exception to higher-level routines. It allows the handling of exceptions at different levels in the program hierarchy.
In COBOL, a record represents a ___________ data structure.
- Hierarchical
- Linear
- Relational
- Sequential
In COBOL, a record represents a Sequential data structure. Sequential records are stored one after the other, and each record contains fields that represent the data elements in a specific order.
In COBOL, a multi-dimensional array is often referred to as a _____ array.
- COMP
- GROUP
- INDEX
- OCCURS
In COBOL, when you define a multi-dimensional array, you use the OCCURS clause to specify the number of occurrences for each dimension. This creates a matrix-like structure, often referred to as an OCCURS array.
You are tasked with implementing a COBOL program that calculates employee bonuses based on performance ratings. Which COBOL statement or construct from the Procedure Division would you use for this task?
- EVALUATE statement
- INITIALIZE statement
- PERFORM...THRU
- SEARCH statement
The EVALUATE statement in COBOL is suitable for handling multiple conditions, making it ideal for calculating employee bonuses based on various performance ratings. It allows for a structured way to evaluate different conditions and execute corresponding code blocks.
In COBOL, what is the purpose of the FUNCTION statement when using intrinsic functions?
- To call built-in intrinsic functions
- To declare variables
- To invoke user-defined functions
- To specify file operations
The FUNCTION statement in COBOL is used to call built-in intrinsic functions. It enables the use of predefined functions like NUMVAL, EDIT, and others, providing a convenient way to perform specific operations on data within a COBOL program.
The process of systematically finding and correcting errors in a COBOL program is known as _____.
- Compiling
- Debugging
- Testing
- Tracing
Debugging is the systematic process of finding and correcting errors in a COBOL program. It involves identifying and fixing issues to ensure the program functions as intended.
What is the benefit of using an index in COBOL arrays and tables?
- Enhanced data validation
- Improved access and manipulation of data
- Reduced storage requirements
- Simplified syntax
Using an index in COBOL arrays and tables provides improved access and manipulation of data. It allows for efficient retrieval of specific elements, making it easier to work with large datasets and enhancing program performance.
How can duplicate records in a COBOL file be identified?
- By comparing each record with a master file
- By performing a sequential search in the file
- By using the DUPLICATES phrase in the SELECT statement
- By utilizing the ALTERNATE KEY clause
Duplicate records in a COBOL file can be identified by using the DUPLICATES phrase in the SELECT statement. This allows the program to detect and handle records with identical key values efficiently.
What is the primary purpose of the COBOL Procedure Division?
- To declare data elements
- To define the file structure
- To handle program termination
- To specify the processing logic for the program
The COBOL Procedure Division is used to specify the processing logic for the program. It contains the statements that define the sequence of operations to be performed during program execution.
In COBOL, what is the primary purpose of the "NOT ON EXCEPTION" clause?
- To ensure that exceptions are handled only once
- To exclude specific exceptions from being handled
- To force the program to terminate on any exception
- To handle exceptions that do not match the specified conditions
The "NOT ON EXCEPTION" clause in COBOL is used to exclude specific exceptions from being handled by the associated exception-handling routine. It allows for fine-grained control over exception handling, ensuring that only relevant exceptions are processed while others are ignored.
