Comparison of Nonnumeric Operands:
A nonnumeric operand can be compared to the other nonnumeric operand according to the rules as shown below:
(i) Fields of Equal Sizes:
The Characters in the equivalent positions are compared to determine the value of the relational condition. The Comparison begins with the leftmost character in both the fields and proceeds in a left to right side manner. If the 2 characters being compared are found to be unequal at any stage, the field containing the biggest characters is considered to be greater. When the characters are only found to be identical does the comparison proceed to the later position on the right. The 2 fields are taken to be equal only when all these pairs of characters have been found to be similar and the rightmost end has been reached.
(ii) Fields of Unequal Sizes:
If the two operands are not of equivalent size, the shorter field is considered to be extended on the right by spaces to make its size equivalent to the longer field and the rules for comparing fields of equal sizes are used.
PROGRAM FOR INDEXED SEQUENTIAL FILE CREATION: We have to write a program to create an Indexed Sequential File in a dynamic mode for Student particulars. Suppose just 3 fields:
WRITE Statement: The WRITE statement for a relative file has the format which is as shown below. WRITE record-name [ FORM identifier ]
INDEXED TABLES: The OCCURS clause that is used to define tables can optionally have an INDEXED phrase. This phrase involves the names of data items which are to be used as sub
LEVEL NUMBERS: The COBOL makes use of the level number concept to explain the hierarchical data structure. A level number is a 2 digit number. The permitted level numbers a
ARITHMETIC VERBS: Most of the problems need some computations to be performed on the input or intermediate data that are numeric in nature. The Arithmetic verbs are used to pe
PROGRAM FOR MASTER FILE MAINTENANCE: We have to write a program to keep the stu-file for which a record has just 2 fields,viz., rno(Roll Number) and name(Student Name). Give t
READ STATEMENT: The aim of this verb is to make available the next logical record from the input file. It is important to note the meaning of the "next" logical record in the
OPEN statement: We know that the processing of a file should start with the execution of an OPEN statement. The file can be opened in any one of the 4 open modes - INPUT, OUTP
RESERVE clause: This clause indicates the number of buffers to be used for the file. Integer-1 specifies this number. ORGANIZATION/ACCESS clause: These two clause
Size: The number of characters or digits needed to store the data item in the memory in termed as the Size of the data item. All the 4 general characteristics explained can
