Daniel, thanks a lot. I see how it's working now. I am pretty new 
at GIS stuff. Here is a related question. I have another TAB file 
which has no geometry info in it, and crashes mapserver when I 
use it as an OGR connection. I think it's supposed to be joined 
with the table shown above. It's signature looks like this. How 
would I do a "join" to display, for instance the Address field of 
Eslocs.TAB?

INFO: Open of `Eslocs.TAB'
using driver `ESRI Shapefile' successful.

Layer name: Eslocs
Geometry: None
Feature Count: 83
Layer SRS WKT:
(unknown)
NAME: String (40.0)
ID: Integer (11.0)
ADDRESS: String (40.0)
PHONE: String (10.0)
MAPADD: String (40.0)
OGRFeature(Eslocs):0
   NAME (String) = A. Montoya
   ID (Integer) = 321
   ADDRESS (String) = 24 Public School Rd Tijeras
   PHONE (String) = (null)
   MAPADD (String) = 24 Public School Rd
