RE: RPG overloading (was RPGV?)

As Paul mentioned, technically that's casting. But the premise is
the same: The resulting value is populated based on the variable type
of the receiver. The compiler can easily determine what type the
target is and populate it accordingly.

It's overloading. Casting is the practice of causing a function's
return
type to be converted to something else after the fact. Overloaded
return-type functions (possible in JAVA, by the way, and I think I C++)
actually (and "natively") return different types of result based upon
the
type of result requested.

This isn't totally accurate. Method overloading in Java depends on the
number and type of the parameters, not the return value. While
overloaded methods can return different types, the return type itself
is not sufficient to overload a method. This is true for C++ as well.

Sorry; I'm sure you're right. But regardless how it's done, the procedure
(function) is capable of sending varying types of result in Java and in C++.

Also, while I'm here, I apologize for misreading your prior message, and now
see that we are in agreement about what is casting and what is overloading.
