Don, you're probably on the right track with the database. I'm not sure why you'd torture yourself with C in this case - the string processing, architecting, etc, won't be fun -, KGS does very well with Java. Christian Don Dailey wrote: Hi Remi, I noticed that when CGOS first came up,

I'm extremely comfortable with C and I think the server CGOS runs on is one of those virtual machines without a whole lot of power or memory. There is no way I'm going to bring up a java runtime. C is the just about the only reasonable way to write a truly efficient program, in terms of
