Record number

[Walter D Vaughan Jr]

I used to get worried about casting @rn as 8,.0 but somehow a light bulb
just went off in my head. As Ken basically shared @rn is a *calculated* (or
to make it seem more 2013, a *virtual*) field and is used when it is needed.
It's not stored data like @CB or @UD. The only place it kinda persists is
inside of indexes and $diety knows KB and just a few others on this planet
can converse intelligently about index data structure.

Super deluxe posting points for anyone to post actual code that groks the
contents of a  filePro index within a processing table and does something of
value with it.
