Comparison of the Numeric Operand with Nonnumeric Operand: The numeric operand can be compared to the nonnumeric operand subject to the restrictions which are as follows.
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:
REDEFINES CLAUSE: At times it may be found that two or more storage regions defined in the DATA DIVISION are not in use concurrently. In such situations only one storage regio
