When defining an indexed file in COBOL, what information is typically included in the file's SELECT statement?
- FILE STATUS clause, DATA RECORD clause, FILE-CONTROL paragraph, and ACCESS mode
- FILE STATUS clause, RECORD clause, ACCESS mode, and ORGANIZATION mode
- FILE STATUS clause, RECORD clause, FILE-CONTROL paragraph, and ACCESS mode
- RECORD clause, ORGANIZATION mode, ACCESS mode, and INDEXED BY clause
The SELECT statement for an indexed file in COBOL typically includes the FILE STATUS clause for error handling, the RECORD clause for specifying the structure of records, the FILE-CONTROL paragraph to manage file attributes, and the ACCESS mode to indicate sequential or random access.
When performing date arithmetic in COBOL, you often use the _____ verb.
- ADD
- COMPUTE
- DIVIDE
- MULTIPLY
When performing date arithmetic in COBOL, the COMPUTE verb is commonly used. It allows for the manipulation of date fields, facilitating calculations involving days, months, and years.
When a data item is defined with the OCCURS clause and a DEPENDING ON phrase, the actual number of occurrences is determined at ____________.
- Compile time
- Declaration time
- Execution time
- Initialization time
The actual number of occurrences for an OCCURS clause with a DEPENDING ON phrase is determined at execution time, not during compilation. The DEPENDING ON phrase allows the size to be specified dynamically during program execution.
One common use of the REDEFINES clause is to reinterpret binary data as ____ data or vice versa
- Alphanumeric
- Display
- Numeric
- Packed-decimal
The REDEFINES clause is frequently used to reinterpret binary data as numeric data or vice versa, allowing the same memory space to be used for different data representations.
In COBOL, what is a "multidimensional array" in the context of the OCCURS clause?
- An array with a DEPENDING ON clause
- An array with a fixed number of elements
- An array with multiple dimensions defined using nested OCCURS clauses
- An array with varying sizes for each dimension
In COBOL, a "multidimensional array" is created by using nested OCCURS clauses, allowing the definition of arrays with multiple dimensions. This provides a structured way to organize and access data in a table-like structure.
When working with relative files, the _____ clause is used to specify the maximum record size.
- MAXIMUM RECORD SIZE IS
- RECORD CONTAINS
- RECORD SIZE IS
- RELATIVE KEY IS
When working with relative files in COBOL, the "RECORD CONTAINS" clause is used to specify the maximum record size. This clause helps allocate the necessary storage for the records in the relative file.
When declaring a table in COBOL, which clause specifies the number of occurrences?
- DEPENDING ON
- INDEXED BY
- OCCURS
- REDEFINES
The OCCURS clause in COBOL is used to declare a table and specifies the number of occurrences or elements in that table. It defines the size of the table and the number of times data is repeated within it.
You are developing a payroll system in COBOL. Which arithmetic operation should you use to calculate the gross salary of an employee based on their hourly wage and hours worked?
- ADD
- COMPUTE
- DIVIDE
- MULTIPLY
To calculate gross salary, you should use the MULTIPLY operation to multiply the hourly wage by the number of hours worked, giving the total amount earned. ADD, DIVIDE, and COMPUTE are not appropriate for this specific calculation.
To prevent duplicate records from being inserted into an indexed file, you can use the _____ clause in the file description.
- DISTINCT
- NO-DUPLICATES
- NO-DUPS
- UNIQUE
The NO-DUPLICATES clause in the file description of an indexed file ensures that duplicate records with the same key value are not allowed, preventing the insertion of records with duplicate keys.
Exception handling in COBOL often involves the use of the _____ clause.
- EXCEPTION
- NOT EXCEPTION
- NOT ON EXCEPTION
- ON EXCEPTION
Exception handling in COBOL often involves the use of the ON EXCEPTION clause. This clause allows the program to specify actions to be taken when certain exceptional conditions occur during program execution.
