          Meal numbers in recalls that were complete and reliable (DRPSTAT=1)   
          always begin with meal number=1; meal numbers increase by one for each
          consecutive meal or snack reported during the dietary interview.  If a
          recall was coded reliable, but incomplete, (DRPSTAT=2) the meal       
          numbers may not be consecutive; information is reported for meals that
          were reported during the dietary interview.  Meal numbers are not     
          sorted by the time of day.

          Every food has a food number.  Foods are numbered within meals.  If   
          the recall was coded complete and reliable (DRPSTAT=1), the first food
          in each meal has a food number=1, and the other foods reported in the 
          same meal are numbered consecutively.  If the recall was coded        
          reliable, but incomplete, (DRPSTAT=2) the food numbers may not be     
          consecutive; information is reported for all foods that were reported 
          by the respondent.

          Foods are comprised of one or more components.  An example of a single
          component food is a slice of bread.  A sandwich is an example of a    
          multi-component food or combination food; in this example, the        
          component foods consist of bread and sandwich filling components.     
          If a recall was coded reliable and complete (DRPSTAT=1), all          
          components are numbered consecutively within a given food; the        
          component numbering sequence for the first food begins with component 
          number=1 and increases by one for each additional component in the    
          food.  The numbering sequence is repeated for each additional food    
          reported.  If the recall was coded reliable, but                      
          incomplete,(DRPSTAT=2) the component numbers may not be consecutive;  
          information is reported for the components that were reported by the  
          respondent.

          NCHS assigned combination food codes to 7 of the 15 combination food  
          types.  DRPCCODE text descriptions are found in a look-up table called
          "Codebook".  Special documentation was prepared for the CFF to provide
          data users with additional information on combination foods coding.   
          The coding information is found in an Appendix section to the CFF.
