   The National Health Interview Survey (NHIS) 2019;
 
                 Sample Adult Imputed Income data file
 
   This program loads the NHIS sample adult imputed income ASCII data file downloaded from the
   NCHS website (https://www.cdc.gov/nchs/nhis/index.htm) to a Stata dataset.
 
   The program creates descriptive variable labels and formats with meaningful
   category labels.  It sets the variable lengths and uses input statements to
   read in the data.
 
   BEFORE RUNNING THIS PROGRAM, PLEASE:
    - Create a folder called C:\NHIS2019 (on a machine running Windows)
    - Download the sample adult imputed income ASCII file to the folder C:\NHIS2019
      (on a machine running Windows)
 
   Running this program will replace the log file and the dataset in the default
   directory, if present.
