What does the "IDENTIFICATION DIVISION" in a COBOL program contain?
- Execution logic
- File descriptions
- Program name, author, date written, and other identifying information
- Variable declarations
The "IDENTIFICATION DIVISION" in a COBOL program contains information about the program, including its name, author, date written, and other identification details. It provides metadata about the program.
The "IDENTIFICATION DIVISION" of a COBOL program typically contains information such as the program's _____
- All of the above
- Author
- Date of Creation
- Version
The "IDENTIFICATION DIVISION" in COBOL includes information like the author's name, version of the program, and the date of creation. It provides details about the program's identification.
Which COBOL data type is used to store whole numbers without a fractional part?
- DECIMAL
- FLOATING-POINT
- INTEGER
- STRING
The INTEGER data type in COBOL is used to store whole numbers without any fractional part, making it suitable for integer values.
A _____ is a tool or software used in COBOL debugging that provides detailed information about the program's execution.
- Debugger
- Inspector
- Profiler
- Tracer
In COBOL debugging, a "Tracer" is a tool or software that provides detailed information about the program's execution flow. It helps programmers analyze the sequence of statements executed, aiding in identifying errors and improving program efficiency.
What is the role of interfaces in Object-Oriented COBOL, and how are they different from classes?
- Interfaces are used only for input/output operations.
- Interfaces can be instantiated like classes.
- Interfaces define common behavior, and they cannot have attributes.
- Interfaces have the same characteristics as abstract classes.
In Object-Oriented COBOL, interfaces define common behavior that can be implemented by multiple classes. Unlike classes, interfaces cannot have attributes; they only declare methods. Classes can implement multiple interfaces, enabling them to exhibit behavior from different sources. Interfaces promote a higher level of abstraction and facilitate code modularity and flexibility.
Your COBOL program must handle different status codes for customer orders. Which COBOL feature would help you define condition names for these status codes?
- CONDITION
- LEVEL NUMBER
- OCCURS
- VALUE OF
The CONDITION name is used in COBOL to represent a condition that can be tested during program execution. It allows you to define symbolic names for specific values, like status codes for customer orders, making the code more readable and maintainable.
You are writing a COBOL program to calculate the total cost of items in a shopping cart. Which type of COBOL variable would you use to store the individual item prices?
- PIC 9(3) DISPLAY
- PIC 9(5)V99 COMP-3
- PIC S9(4) USAGE COMP
- PIC X(10)
For storing monetary values like individual item prices in a COBOL program, PIC 9(5)V99 COMP-3 is suitable. This usage efficiently represents decimal numbers and ensures accurate calculations.
The CONTINUE statement is often used in COBOL error handling to ___________ the program's normal flow.
- Bypass
- Interrupt
- Maintain
- Resume
The CONTINUE statement in COBOL is used to resume the program's normal flow after error handling. It allows the program to continue executing subsequent statements in the same scope.
What is the purpose of the OCCURS DEPENDING ON clause in COBOL tables?
- It allows the number of occurrences for the table to be determined dynamically at runtime
- It defines the maximum number of occurrences for the table
- It indicates that the table is part of a nested structure
- It specifies the initial values for the table elements
The OCCURS DEPENDING ON clause in COBOL tables allows the number of occurrences for the table to be determined dynamically at runtime based on the value of a preceding data item. It provides flexibility in handling varying amounts of data.
The _____ clause in COBOL is used to specify the key structure when defining a VSAM file.
- FILE-CONTROL
- KEY
- RECORD
- SELECT
In COBOL, the KEY clause is used within the FILE-CONTROL section to specify the key structure when defining a VSAM file. It defines the data item or items that make up the primary or alternate key of the file.
