* Method 1: Raad CSV file without format data
filename webdat url "http://bigblue.depaul.edu/jlee141/econdata/health_data/NATS/nats_2013_finalcpl_6_weighted.csv" ;
proc import datafile=webdat out = NATS 
     DBMS = csv  replace ; 
run ;
proc contents data= NATS ; 
run ;


* Method 2: Read SAS Dataset and use Format Library 

This program (formats_for_nats_2013_finalcpl_6_weighted.sas) creates the formats
catalog for nats_2013_finalcpl_6_weighted.sas7bdat.

Instructions for Windows users:

1. Create a folder for your files, e.g. c:\sasfiles
2. Place nats_2013_finalcpl_6_weighted.sas7bdat and formats_for_nats_2013_finalcpl_6_weighted.sas
   in the folder
3. Edit the libname statement in formats_for_nats_2013_finalcpl_6_weighted.sas so that
   it refers to the folder, e.g.: libname library 'c:\sasfiles'
4. Open and run formats_for_nats_2013_finalcpl_6_weighted.sas.  This will create
   the formats catalog, "formats.sas7bcat" in that folder.
5. You may now use nats_2013_finalcpl_6_weighted.sas7bdat any way you
   like, for example the following program will create a frequency listing:

   libname library 'c:\sasfiles';
   proc freq data=library.nats_2013_finalcpl_6_weighted; 
      tables _all_;
   run;

   Note that by using the name "library" for your libname when inputting the 
   data, SAS will automatically look in that same location for the formats
   catalog.  Otherwise, you would need to use a "fmtsearch" option to tell
   SAS where to look for the formats catalog.
