     Type:  defect        |      Status:  new                      
 Priority:  major         |   Milestone:  6.4.0                    
Component:  default       |     Version:  6.3.0                    
 Keywords:  dbf division  |  
--------------------------+-------------------------------------------------
 The help page on the dbf driver says "Arithmetic expressions using
 constants and field values are allowed in condition clauses and in the RHS
 of assignments".

 I can confirm that these work:

 {{{

 v.db.update map=ilots col=prop_popmo value='P_UNDER_5+P5_TO_9'
 v.db.update map=ilots col=prop_popmo value='P_UNDER_5-P5_TO_9'
 v.db.update map=ilots col=prop_popmo value='(P_UNDER_5+P5_TO_9)*TOTAL_POP
 }}}


 However,


 {{{
 v.db.update map=ilots col=prop_popmo value='(P_UNDER_5+P5_TO_9)/TOTAL_POP'
 }}}


 gives me the following error:

 {{{

 ERROR: This should not happen: got a wrong expression structure after
        parsing.
 dbmi: Protocol error
 ERROR: Error while executing: 'UPDATE ilots SET
        prop_popmo=(P_UNDER_5+P5_TO_9)/TOTAL_POP
        '
 }}}
