Sorry, for bugging you. But I want to understand this engine, but it is hard 
to understand for a small programmer.
I learning by doing with some faults. I know.

But I use the sprintf function in some C++ String classes like:

AnsiString a;
a.sprintf("I'am to small with %d!", 1);
ShowMessage(a);

....I miss this function and want to implement it.
sprintf in global object is like C and not like C++ or Java, when I want to 
use it for a "String".

Last chance: "poor-man's namespace" :-(

Thx Blaubaer
