When date values in the form of ddmmyyyy are read with the ANYDTDTEw.
informat, missing values are generated for days between the 16th and
21st of the month, inclusive.  For example:

  data a;
    input date anydtdte8.;
    format date mmddyy10.;
  datalines;
  15122005
  16122005
  17122005
  21122005
  22122005
  ;
  proc print data=a;
  run;

produces:

  Obs         date

  1     12/15/2005
  2              .
  3              .
  4              .
  5     12/22/2005

The circumvention is to use the DDMMYY8. informat instead.
