IBM COBOL Mocktest Quiz

The given correct answer, "01," indicates the highest level in the data hierarchy and refers to the entire data set contained within it. This level represents the most general and encompassing category of data, which includes all the individual data points and subsets within it.

The given correct answer is "True."

After the execution of one of the when clauses, the control is automatically passed on to the next sentence after the EVALUATE statement. This means that there is no need for any extra code to transfer control to the next sentence. Therefore, the statement is true.

The REDEFINES clause in COBOL is used to allow the same storage location to be referenced by different data names. This means that a single memory location can be used to hold different values, depending on which data name is being used to access it. This can be useful in situations where different data items need to share the same memory space, or when a single data item needs to be interpreted in different ways. The other options mentioned in the question are not true regarding the REDEFINES clause.

The given answer, DATA DIVISION, is correct because the question is asking which division is present in the LINKAGE-SECTION. The LINKAGE-SECTION is a part of the DATA DIVISION in COBOL programming language. It is used to define the data items that are passed between programs or subprograms. Therefore, the correct answer is DATA DIVISION.

The given statement "MOVE A B TO C" is not a valid syntax in any programming language. In order to assign the value of A to C, the correct syntax would be "MOVE A TO C". Therefore, the operation cannot be performed due to improper syntax.

The correct answer is COMP3 because PIC S9 (4) indicates that the data is a signed numeric value with a length of 4 digits. COMP3 is a binary format that is commonly used to store packed decimal values, which are numeric values with a fixed number of decimal places. Therefore, COMP3 is the most appropriate choice for storing a signed numeric value with 4 digits.

If the result of an arithmetic operation exceeds the largest value that can be accommodated in the result field, it is considered a SIZE ERROR. This means that the result is too large to fit within the designated storage space, causing an error in the calculation.

Among the given options, the correct representation related to the '.' picture character in COBOL is:

01 COST PIC 999.99.9

In COBOL, the '.' (period) is used as a separator to define the picture clause for numeric data items. The '9' represents a numeric digit, and the '.' is used to separate different parts of the numeric format. The format "999.99.9" indicates a numeric field with three digits to the left of the decimal point, two digits to the right of the first decimal point, and one digit to the right of the second decimal point.

In the given statement, it is stated that every data name used in the program must be defined in the PROCEDURE DIVISION. However, this statement is false. In COBOL, data names can be defined in various divisions, including the DATA DIVISION, FILE SECTION, and WORKING-STORAGE SECTION. The PROCEDURE DIVISION is responsible for defining the program's logic and does not necessarily involve defining data names.

In COBOL, a word cannot contain a blank. A COBOL word is a sequence of characters that can include letters, digits, and special characters, but it cannot contain spaces or blanks. Therefore, the correct answer is False.

The given answer is column 7. This is because the question asks for the column position where we can write continuation. The options provided are 8-11, 73-80, 7, and none. The first two options are ranges of columns, so they cannot be considered as a single column position for continuation. The option "none" implies that there is no column available for continuation, which contradicts the question. Therefore, the correct answer is column 7.

The OCCURS clause eliminates the need for separate entries for repeated data items. This clause is used in COBOL programming language to define arrays or tables. It allows multiple occurrences of a data item to be stored in a single entry, reducing the need for separate entries for each occurrence.

The REDEFINES clause cannot appear in the same data description entry which contains an OCCURS clause. The REDEFINES clause is used to define two or more data items that occupy the same storage location, while the OCCURS clause is used to define a table or array. These two clauses cannot be used together in the same data description entry. Therefore, the given statement is false.

This statement suggests that the feature or concept being described gives the flexibility to define data-names with the same name. The correct answer, "QUALIFICATION," could be referring to a programming language or software feature that allows for the creation of variables or data structures with identical names. This flexibility can be useful in certain situations where multiple variables or data structures with the same name are needed.

A COBOL word cannot have national characters.

The given code snippet is written in COBOL programming language. In COBOL, a PIC (Picture) clause is used to define the format and type of a data item. In this case, the PIC clause "$ZZ999" indicates that the variable A is defined as a 5-digit alphanumeric field, where the first 2 characters are alphabets and the next 3 characters are numeric.

The MOVE statement is used to assign a value to a variable. Here, the value 985 is being moved to the variable A.

Therefore, the output would be "$ 985", as the variable A is defined with a leading dollar sign and 3 spaces before the numeric value.
