Where they do _not_ reside is on mass storage. It most certainly _does_ reside in primary storage (a.k.a. "memory," a.k.a. RAM). The fact that the information is derived on-demand from the current state of the system is only incidental and not fundamentally different from the constituents of any more ordinary file system. > Bill Anderson > WW7BA Randall Schulz -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
