Hi Michael,

Download the PICmicro® 18C MCU Family Reference Manual... or just the chapters you need from here;

There's a whole section on table read/write with detailed explanations that should answer every question you have.

Much easier than me re-typing it all. If you have questions after reading section 8 let me know.
