The more detailed readme file for the SF3 "conversion kit" is the sf3cnvt.txt
file found inside cnvtkit.zip archive.  You need to download this (cnvtkit.zip)
file in binary mode from
http://mcdc2.missouri.edu/data/sf32000/Tools/ .
 (The unzipped versions of the file are also available in this same directory,
but it will be faster to transport the zip archive and unzip on your side.)       

                                                                     
You need to download (individually or as part of the .zip file) each of the .sas
 modules and the cnvtsf3.txt file (a "readme" for the conversion modules.)
There are two versions of the convert routine and I think most users will find
the cnvtsf3_windows.sas version preferable.  It differs from cnvtsf3.sas in
that:
    -It has model path values suitable for Windows rather than Unix.
    -It has a new %include statement that includes the new formats.sas module.
The latter has the proc format code for defining $fplace, $fipstab and $sumlev
as used in various parts of the conversion.

NOTE:  Some of you may have downloaded an earlier version of the convert routine
that worked just fine back then.  The Bureau made a change to the later
files and we had to alter the program to reflect that change.  Here is the SAS
statement that needs to be edited (for those of you who already have the
software but are getting an error message about invalid LOGRECNO values  when
the program encounters the first 085 summary level records):
  *--Set flag to indicate whether this geographic summary level will have data
for the CT tables--;
    _readCT= ( sumlev not in ('Z85','090','150','154') );  *<--note that 085,
tract/UR is NOT!(now)  considered sub-tract-;
