Each data item has a "flag" associated with it to describe any special
conditions applicable.  Where normal data are shown, the flag field is
blank.  Flags B, D, N, S, W, X, and Y indicate that the data are not 
shown and the data field contains only a zero.  Flags appear above or 
beside related data items.
                            
B         Bracket (see total with T flag in preceding cell)
D    (D)  Data withheld to avoid disclosing operations of individ
F         Data subject to footnote (text unavailable here)
