Users working with 1992 Census of Agriculture CD-ROM 1c,
    State data, may obtain an error message when working with
    the historical state summary file AG_ST_01.dbf and selecting
    records by state.

    proc ndxcheck line 338 open error !ag_stx0.ndx

    This error, caused by the omission of a planned index from
    the CD-ROM, can be avoided by putting a new .cti (catalog of
    indexes) file in the \EXTRACT directory of your hard disc.
    This is installed automatically by the INSTALL program on
    Economic Census CD-ROM 1f (Sep 95).  Alternatively, the file
    may be obtained from the Census BBS.

    1. Download the file AG92SSUP.EXE

    2. At a DOS prompt, type AG92SSUP C:\EXTRACT
       which will uncompress ag92_st.cti and ag92_st.ndx onto your
       hard disc.

    3. If you need to work with Ag CD-ROM 1c on more than one
       computer, simply copy the two files ag92_st.* to the
       \extract directory of the using computer.
