In a COBOL program, if you have a numeric data item defined as USAGE COMP-3, what is the effect of applying the REDEFINES clause to it?
- It allows the same data to be referenced using different data descriptions
- It converts the COMP-3 data to COMP data
- It defines a new data item with the same name
- It is not allowed to use REDEFINES with COMP-3
The REDEFINES clause in COBOL allows the same storage space to be referenced using different data descriptions. When applied to a numeric data item with USAGE COMP-3, it enables sharing the same memory location with other data items, potentially of different types.
