 Arguments

 Returns

        DBSETFILTER()   always returns NIL.    

 Description

      This function masks a database so that only those records that meet
      the  condition prescribed by the expression in the code block
      <bCondition>  and literally expressed as <cCondition> are visible.
      If <cCondition> is not passed to this function,then the DBFILTER()
      function will return an empty string showing no filter in that work
      area  which in fact,would be not correct.

      USE Tests NEW
      DBSETFILTER({|| Tests->Id <100},"Tests->Id <100")
      DBGOTOP()
