Unbounded Arrays

I’m calling a Natural subprogram on a MVS mainframe from Windows/.NET application. I’m trying to reduce the length of our messages on the network. Natural 3.1 can handle unbounded arrays but it is not supported for the .NET wrapper (I’m using V7.1.1 of the EntireX Workbench).
Is it supported in any future version?

From the v7.2.1 release notes:

.NET Wrapper Enhancements
Complete IDL Data Type Support
Full IDL data type support is now provided. New supported data types include KV and K, unbounded arrays, multi-dimensional arrays of groups and structs. See EntireX IDL-to-.NET Mapping for more information.
