Index shared by multiple tables

See this idea on ideas.ibm.com

It can be useful to be able to access the same position in a synchronized way in several tables.
In this case it is necessary to use an indice (numeric data item) that is independent of each table.
However, for performance reasons, it is best to use indexes (address offset to item in a array) to access items in a table, but an index can not be shared by multiple tables.

We propose to create the notion of index shared by several tables:
- at the Cobol source level, only one "logical" index is manipulated
- at the binary level, the "logical" index is actually a vector of "physical" index consisting of as many values as there are tables that share this "logical" index
- "SET index" instructions at the Cobol source level modify each value of the vector "physical" index

    This RFE is being rejected because is not compatible with any COBOL Standard implementation.

    We require more time to investigate this RFE.

    At binary level, a field containing the current row number (indice) can be associated with the vector of index.
    This field can be used in statements involved in comparaison between index and decimal values.
