Java knows managed code? If you are talking about J#, I am sure it does,
but that isn't Java. Nor is RPG.NET the same or even similar to RPG. The
differences are at the syntax level, but in the end it is still .NET with
all of it's limitations (i.e. one platform runtime).

Steve I think you need to define managed code and then relate it to ILE on
i5OS.

managed code is the thing which enforces and ensures the type safeness
of your java or .net code. It is the thing that prevents the buffer
overrun or the error we get in RPG when a parameter contains garbage
or the value of adjacent parameters.

What is kind of an interesting question is what is the difference
between java and .net. and why did java not become as important to
i5/OS applications as .NET has to windows. .NET is very good at
working with Windows APIs and other unmanaged code DLLs. And the .NET
classes are all built to work well with the Windows OS.

I think you will find that i5OS ILE has advantages that managed code
does not (e.g. you DON'T have to all compile down to the same 'sil' code but
instead the language 'interfacing' is offered as a means to the same end).

I dont follow this at all. In Windows you can still use DLLs ( which
are pretty much the equivalent of a SRVPGM ), but no one does. .NET
code is compiled into assemblies, which provide full support for
reflection, reflection being the thing that makes your PR prototype
source obsolete.
