KBTMAKE
     =======

        This program makes a b+tree file from the keydirr.kin file

     for use in the SEEDIS program extract.  The keydirr.kin file 
  
     was made from the keydirr.dat file.



     KEYDIRR.KIN
     ===========

        The editable file has the following format:

           #LEVEL/FLAG
            n/de1/de2/....../den/

     where LEVEL is an area level such as NATION80, COUNTY80, BEA, etc.'
   
     and FLAG is what is known as the areaflag such as FIPS.STATE.

     The de's are the de names that apply to the level and n is the count

     of de's.  The following is a partial listing of sy$seedis:[seedis.extract]
 
     keydirr.kin:

     #BEA/
       1/BEA.REGION/
     #COUNTY/FIPS.STATE
       2/FIPS.STATE/FIPS.COUNTY/
     #AQCR/
       1/EPA.AQCR/
     #WRASA/
       1/WRC.WRASA/
     #SMSA/
       1/FIPS.SMSA/
     #PLACE/FIPS.STATE
       2/FIPS.STATE/FIPS.PLACE/
     #TRACT/FIPS.STATE
       3/FIPS.STATE/FIPS.COUNTY/FIPS.TRACT/


     After editing the file, it must be run through kbtmake to create the

     B+tree file for use in extract.  The file will have an extention *.kbt.

     The program resides in sy$seedis:[seedis.btree].  After making the

     b+tree file, it may be looked at by executing sy$seedis:[seedis.btree]

     bt_look.exe.
