- Actually, I'm cross-referencing one file against another by a
- common field (not exactly relational database but similar idea); the
- field could just as well contain ABCDEFGH as CHCGILCA but the latter

- There was a list (containing some inaccuracies in NPA/NXX/CO name)
- circulating BBSes around here when 312 split, and it contained eight-
- letter abbreviations; don't know if it was deliberately letting me

- In that (probably inaccurate) list I had, every CO in the City of
- Chicago began with CHCGIL, and the suburban ones had abbreviations
- that roughly allowed them to be matched to village names.

- Didn't know that! Wonder if that figures in their distance

- CEV wouldn't count on per-minute cellular charges, but ...)?

- So far, against the list I've had and the list I've maintained by
- hand from Illinois Bell's MSA-1 list, I've at least managed to
- identify the COs; with a little luck I might be able to cull the
- others.

- I would dearly love that, but (1) some service rep told me that
- they no longer keep a copy of the Illinois tariffs available for the
- public (!!! I thought they were required to, and suspect this is
- stonewalling), (2) The ICC will xerox this tome for me for $0.25/page
- (probably a few tens of bux I can't afford), and (3) my bad back would
- keep me from travelling very far or sitting very long to read it
- anyway. And to top that, my handwriting is bad enough after a few
- minutes of writer's cramp that even I wouldn't be able to decipher my
- own scrawl.

- Right on target so far, thanks.
