Hi,

In the EntireX communicator v7.3.2 documentation, section Software AG IDL Grammer - Array Definition, it has the following statement on unbounded arrays.

On the other hand, in the documentation of Natural v6.2.3, section Natural RPC Restrictions and Limitations, it states that

1. No.
2. What is called “Unbounded arrays” in EntireX corresponds to “X-arrays” in Natural. Arrays in Natural using the
