Objet : [EpiData-list] second try: order of missing values indocument->codebook

Didn't hear from anyone, so I'm trying again (sorry).
  
  I have been creating a dataset using epidata. I was looking through the  documentation->codebook to get a sense of the distribution ofvalues  for thevariables. I just noticed that the missing values (.) appear at  an almost random point in the otherwise ordered list (in this  example,between 9 and 10).  I compared the codebook with SAS  tables and the data appear to be correct.
  
               tabulation:   Freq.    Pct.   Value   Label
                                 2     3.8       3   
                                 1     1.9       4   
                                 2     3.8       5   
                                 6    11.5       7  
                                 7    13.5       8  
                                 7    13.5       9  
                                 6    11.5       .  
                                21    40.4      10  
  
  
  
    Any ideas why this might happen?
  
  thanks.
