The CONTINUE statement is primarily used for __________ error handling in COBOL programs.
- General
- Specific
- Structured
- Systematic
The CONTINUE statement in COBOL is primarily used for specific error handling. It allows the program to continue processing even if an error condition is encountered, providing a mechanism for graceful recovery.
The _____ clause in COBOL allows you to redefine a data item to have a different data type.
- ALTER
- OCCURS
- REDEFINES
- RENAMES
The REDEFINES clause in COBOL allows you to redefine a data item to have a different data type. This enables efficient memory utilization by sharing storage space between different data items.
Which file organization type is best suited for situations where records are frequently added and deleted?
- Indexed organization
- Line sequential organization
- Relative organization
- Sequential organization
Indexed organization is best suited for situations where records are frequently added and deleted. It provides efficient access to records through keys, allowing for dynamic record management.
When working with indexed files, the ______ clause is used to define the structure of the index file.
- INDEX
- KEY
- ORGANIZATION
- RECORD
In COBOL, the ORGANIZATION clause is used to define the structure of the index file when working with indexed files. It specifies whether the file is sequential or indexed and sets the rules for accessing data efficiently.
How do you perform date arithmetic in COBOL, such as adding or subtracting days from a date?
- COBOL does not support date arithmetic
- Use the ADD and SUBTRACT statements
- Use the intrinsic function DATE-OF-INTEGER
- Utilize the COMPUTE statement
In COBOL, you perform date arithmetic, such as adding or subtracting days from a date, by using the ADD and SUBTRACT statements. These statements allow you to manipulate date fields with ease.
When using the READ verb in COBOL, what happens when the end-of-file (EOF) condition is encountered?
- The program ignores the EOF condition
- The program terminates abruptly
- The system automatically opens the next available file
- The system raises an end-of-file (EOF) status code
When the READ verb in COBOL encounters the end-of-file (EOF) condition, the system raises an end-of-file status code. This allows the program to handle the conclusion of file processing gracefully.
You are working on a COBOL application that handles variable-length records in an employee database. Each record contains a variable number of dependents. How would you dynamically calculate the length of each record based on the number of dependents?
- DEPENDING ON
- LINAGE IS 66
- OCCURS
- RECORDING MODE IS V
The DEPENDING ON clause in COBOL is used to dynamically calculate the length of a record based on the value specified in another field. In this case, the number of dependents would determine the length of each record, allowing for flexibility in handling variable-length data.
When using a relative file organization, the _____ number is used to access records.
- File
- Index
- Record
- Relative
In a relative file organization in COBOL, the relative record number is used to access records. This number specifies the position of the record relative to the beginning of the file, allowing for direct access to specific records.
When working with arithmetic operations in COBOL, the ________ statement is used to control the flow of execution based on conditions.
- ADD
- EVALUATE
- MOVE
- PERFORM
The EVALUATE statement in COBOL is used for conditional execution based on the result of arithmetic operations. It allows for a concise and readable way to handle multiple conditions.
You are working on a COBOL project that involves reading and processing multiple bank transactions, each with various details like transaction type, date, and amount. How would you structure the data using group data items in COBOL?
- Arrange the data using JUSTIFIED alignment
- Group each transaction detail under a single name using a GROUP data item
- Use OCCURS to repeat the transaction details for each record
- Utilize REDEFINES to redefine the transaction details
In a COBOL project involving multiple bank transactions, grouping each transaction detail under a single name using the GROUP data item is a suitable approach. This allows you to organize and access related information like transaction type, date, and amount efficiently.
In COBOL, the ________ statement is used for performing complex arithmetic operations.
- ADD
- COMPUTE
- MOVE
- PERFORM
The COMPUTE statement in COBOL is used for performing complex arithmetic operations involving multiple variables. It allows for the execution of arithmetic expressions with various mathematical operators.
Your COBOL program handles financial data, and you need to convert numeric amounts to their equivalent string representations. Which COBOL intrinsic function is suitable for this task?
- FUNCTION NUMVAL
- FUNCTION NUMCHECK
- FUNCTION NUMERIC
- FUNCTION EDIT
The FUNCTION EDIT intrinsic function in COBOL is suitable for converting numeric amounts to their equivalent string representations. It provides formatting options for numeric data, making it useful in financial applications.
