                Auxiliary files for USA COUNTIES 1992 CD-ROM

****************************************************************************
 
The file USACOAUX.EXE contains auxiliary files (in compressed form) to allow
the EXTRACT software to work with the U.S.A. Counties 1992 CD-ROM issued by
the Census Bureau.  You must also install EXTRACT version 1.4a (issued
November 1992) or later.
 
**************************************************************************** 
 
** Installing these files for use with EXTRACT ** 
 
1.  Create a subdirectory for the auxiliary files, preferably under the
    EXTRACT directory, and make this the current directory:

       C:
       CD \EXTRACT
       MD USACOAUX
       CD USACOAUX

2.  Uncompress the auxiliary files onto your hard disk:

       a:USACOAUX                   <ENTER>
 
    [This command assumes that you have USACOAUX.EXE on a diskette in your a:
    drive.  If you are installing off another drive or subdirectory,
    substitute the appropriate designation for "a:" above.]

    USACOAUX.EXE is a "self-extracting" archive containing catalog, data
    dictionary and other auxiliary files that EXTRACT needs in order to
    select and display data from the U.S.A. Counties CD-ROM.

** Starting EXTRACT to work with USA Counties files ** 
 
1.  Make the directory containing EXTRACT.EXE the current directory: 
 
       CD \EXTRACT 
 
2.  Start the program. 
 
       EXTRACT                   <ENTER> 
 
You will be asked to specify some drives and directories.

3.  You must specify a CD-ROM drive letter.  This is the letter assigned when
    the reader was installed; often, the reader is assigned the letter "L".

4.  You also will be asked to specify a "work directory."  This is any
    directory on your hard disk (e.g., C:\EXTRACT\WORK), that EXTRACT can
    use to store temporary files; be sure to create the directory before
    attempting to use it in EXTRACT!

5.  When the system asks for the location of auxiliary files, specify the
    subdirectory where you installed the auxiliary files for the CD-ROM you
    are using, e.g., C:\EXTRACT\USACOAUX.

6.  Confirm those selections with <Y>es or <S>ave.  If you <S>ave, the system
    will ask you to name a command that will let you skip these steps in the
    future.  The name EXUSACO will be suggested, but you may use anything you
    want.  Just use a different one for each type of CD you have.
