Hi Erik,

Well, JVP already spilled the beans on how I know some of this stuff, but if you can find it, there was a FoxPro 2.0 DOS book that explained this in a lot of detail if I recall. I've got no idea what the title is, but one of the many authors was Jeff Winchell and Dave McClanahan was also a contributor. Dave was the developer that Fox brought in to do rushmore.
