What 'index'?

If you are talking about INDEX variables in COBOL, this information from the DISPLAY statement in the Enterprise COBOL Language Reference manual is relevant:

identifier-1
Identifier-1 references the data that is to be displayed. Identifier-1 can reference any data item except an item of usage PROCEDURE-POINTER, FUNCTION-POINTER, OBJECT REFERENCE, or INDEX. Identifier-1 cannot be an index-name.

If you are not talking about INDEX variables, you will need to explain more about what you mean.

An INDEX is used at the time of defining a COBOL Table, that's what I am talking about.

Thanks Robert. That's what I meant but in the quote what is the difference between INDEX and index-name? Are they not just same?

When you referred to the COBOL manual what did you find out?

Nope -- indexes can be defined with USAGE INDEX or they can be defined with INDEXED BY in a table definition.

Thanks, got it.
