Phil,

By a modern language, I mean one that allows modern techniques.

Strings are defined as a class. All string functions, including "copy"
execute as calls to methods of the string class.  In RPG  the copy of a
string executes as a single MI CPYBLAP instruction. In C++ the same copy
will execute as a function call, memory alloc, byte by byte copy. Much more
cpu is needed.

In a modern language data members of a data structure are "Set" and "Get"
using class methods. In RPG, the data members are accessed directly.

If you follow this methodology in the design of your appl, you wind up
encapsulating and abstracting all over the place.

Much more cpu is needed.
