RE: Overloading in RPG.

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

Some people would argue that overloading is syntactic sugar.  I'm neutral.
Generally overloading is used to do something that is different in detail,
not totally different. 

The most common example of overloading would be to accomodate default
arguments without having to account for their being missing.  The const
keyword allows a limited kind of overloading because it allows implicit type
casting of parameters. Arithmetic operators in RPG and most other languages
are overloaded.  The plus sign is overloaded to add numbers of different
types, and now also can be used for string concatenation. 

In C++ you can overload operators and the only limit to what you can do is
your conscience.  The potential for confusion is limitless.
