NOTES ON USING THE GAZETTEER TABLE
The gazetteer table is formatted so that it may be read directly
into many data management systems on various host computers. All
fields (columns) are separated by commas, and character fields are
enclosed in quotes. Each record consists of 480 bytes, with a
carriage return/line feed sequence in bytes 479 and 480. This allows
the table to be treated as a fixed length record file on hosts which
support this file type and as a normal text file on other hosts.
The structure and content of the gazetteer table are described in
file GAZETTER.TXT located in the GAZETTER directory. A label coded in
the Object Description Language (ODL), providing a formal description
of the index table structure, is located in file GAZETTER.LBL.
For personal computer users a DBASE DBF structure is also provided
in the file GAZETTER.DBF. This file should be copied to magnetic disk
and can then be used to load the GAZETTER.TAB file into DBASE III or
IV with the following commands (assuming the MDIM CD-ROM is loaded
in drive L:):
.USE GAZETTER
.APPEND FROM L:\GAZETTER\GAZETTER.TAB DELIMITED
Once the table is loaded into DBASE, it can generally be automatically
loaded into other data managers or spreadsheets which provide search
and retrieval capabilities.
