When working with an OCCURS clause in COBOL, what does the INDEXED BY phrase allow you to do?
- Associate an index with an OCCURS clause to reference individual occurrences
- Define the initial value of an OCCURS clause
- Determine the data type of the OCCURS clause
- Specify the maximum number of occurrences in an OCCURS clause
The INDEXED BY phrase in COBOL allows you to associate an index with an OCCURS clause. This index can be used to reference individual occurrences within the array, enabling efficient access and manipulation of data.
When using the ENTRY statement in COBOL, variables declared in the called program have a _____ scope.
- COMMON
- GLOBAL
- LOCAL
- SHARED
When using the ENTRY statement in COBOL, variables declared in the called program have a LOCAL scope. This means that they are local to the called program and are not accessible from the calling program or other programs.
In COBOL, how is the REDEFINES clause used to redefine data items?
- By assigning a new value to the redefined item
- By changing the data type of the redefined item
- By specifying a new name for the data item being redefined
- By specifying a new size for the redefined item
In COBOL, the REDEFINES clause is used by specifying a new name for the data item being redefined. This allows the new name to share the storage space of the original data item.
The _____ clause is used to specify the level number of a data item in COBOL.
- DATA
- LEVEL
- OCCURS
- PICTURE
The LEVEL clause in COBOL is used to specify the level number of a data item. It indicates the hierarchical level of the data item within the data hierarchy.
When should you use the OCCURS clause in defining data structures?
- To allocate space for a data item
- To create a loop for processing a group of related data items
- To define a record layout for a file
- To specify the hierarchy of a data item
The OCCURS clause in COBOL is used to create a loop for processing a group of related data items. It allows the repetition of a data item or a group of data items, facilitating the handling of arrays and tables in COBOL programs.
The "PROCEDURE DIVISION" contains the actual _____ of a COBOL program.
- Data declaration
- Execution logic
- File definition
- Identification Division
The "PROCEDURE DIVISION" in COBOL holds the actual execution logic of the program. It includes statements and procedures that dictate the flow of the program and specify the operations to be performed.
In a COBOL program, you need to move a date value from one field to another. Which COBOL statement should you use for this data transfer?
- ACCEPT statement
- INITIALIZE statement
- MOVE statement
- SET statement
The MOVE statement in COBOL is used to transfer data from one field to another. When dealing with date values, the MOVE statement ensures the proper transfer of date information between fields.
In a multi-user environment, two COBOL programs need to access the same file for reading and writing simultaneously. Which file access mode should you select to ensure data consistency?
- DYNAMIC
- I-O
- INPUT
- OUTPUT
In a multi-user environment, the appropriate file access mode is I-O (Input-Output). This mode supports concurrent reading and writing operations, ensuring data consistency when multiple programs access the same file simultaneously.
What does the "CONFIGURATION SECTION" contain in the "ENVIRONMENT DIVISION" of a COBOL program?
- Configuration details for external files and devices
- Procedure details for program logic
- System settings for program execution
- Variable declarations for program data
The "CONFIGURATION SECTION" in the "ENVIRONMENT DIVISION" of a COBOL program contains configuration details for external files and devices, specifying their organization, access modes, and other relevant attributes.
To make a variable accessible across different programs in COBOL, you can use the _____ clause.
- EXPORT
- EXTERNAL
- GLOBAL-STORAGE
- LINKAGE
To make a variable accessible across different programs in COBOL, you can use the EXTERNAL clause. This allows variables to be shared between programs, enabling data interchange between them.
