Hi,

   This is not a Valid definition bcz the USAGE IS INDEX clause is used to provide an optimized table subscript. When a table is the target of a SEARCH statement it must have an associated index item.
     Any item declared with USAGE IS INDEX can only appear in:
        - A SEARCH or SET statement
        - A relation condition
        - The USING phrase of the PROCEDURE DIVISION
        - The USING phrase of the CALL statement

01 WS-VAR USAGE IS INDEX.
it is a valid working storage definition. We can use this variable to store displacement value of another table index. Like normal table index it cannot be used in any computataions and terminal control statements.
