Acknowledged. > C is very old and has changed a lot since it was invented. It's all still either von Neumann or Harvard.

Wirth? I forget. That's exactly what James Gosling et. al. did a very good job about abstracting all of this by inventing Java (the language and the machine specification). That's pretty much why a lot of businesses adopt Java to replace centralized COBOL mainframes in favor of decentralized Java cluster nodes. Oracle, IBM and such know they will be able to make money out of it for decades to come, of course. They just shouldn't have crippled it. > > good luck, > geoff steckel > May the forth be we with you. Thanks. Nice one. -- Christian
