what is JRE?  Jave runtime env?  What CLI does that Java does not is it lets
other languages participate in what MS refers to as the "managed code"
whatever. Java means "Java only" as in "throw away all your RPG and C++
legacy code and programmers". As we see with the demise of SUN, maybe this
Java only approach is not acceptable to the marketplace.  The fact that
debates flair up from time to time on MS newsgroups as to which is MS's
favorite language, C#, VB or C++, shows that CLI is language independent.

So, CLI is basically a re-invention of the JRE only if the construct
"re-invention" is intended to mean "big improvement".

So why was ILE not called BUSB?  CLI= Common Language Infrastructure.
ILE=Integrated Language Environment. Common and Integrated are synonomous ,
Language and Language we all agree are the same and Ifrastructure and
Environment are also synonyms. If they are both named to describe ducks,
shouldnt they both be considered ducks?

Yes, ILE has a run time, what is the structure of a module call stack, how
does the OS resolve to, activate, compare the signature and start to run a
called procedure, aspect to it.

ILE also prescribes a COMMON way of prototyping procedures. A "C" procedure
is interchangeable with an "RPG" procedure.

Speaking as a CLI, managed C++ novice, CLI specifies the common denominator
way that a language should implement classes, events, function pointers (
delegates ) and exceptions.  A managed code C++ class, that is a CLI
compliant class, can be used natively in VB or C# code. It is a bit like ILE
prescribing how data structures are to be declared so that an RPG data
struct could be declared LIKEDS( C struct ).
