Encapsulating a string in a class enables techniques like automatic type
conversion ( ascii to ebcdic to unicode ), all the other string functions
( scan, replace, concat ). Cpu is cheap ( or it should be ).   ( Also the
C++ template functionality works well with classes and functions )

Once you start trying to optimize and mix programing models you really start
to muck things up. Either program the RPG way or the OOP way.
