What is the term for using a tag in the subscript of an array to access elements indirectly?

The correct term for using a tag in the subscript of an array to access elements indirectly is Indirect addressing. This method allows for more flexibility in programming, as it enables the retrieval of array elements using a variable or tag instead of a fixed index.

By employing indirect addressing, programmers can dynamically determine which element of the array to access based on the value of the tag, which can change during the execution of the program. This is particularly useful in scenarios where you need to iterate through the array or when the index is not predetermined at compile time.

Direct addressing refers to accessing an array element using a fixed index, which does not allow for the same level of flexibility as indirect addressing. Dynamic referencing may imply a type of access that involves addressing elements at runtime, but this term is less specific and not commonly used in the context of array subscripting. Static indexing specifically means using a non-variable, fixed index for accessing elements, further differentiating it from the flexibility allowed by indirect addressing.
