        ring R1=Float(),(x,y),dp;
        R1;
      ==> // coefficients: Float() considered as a field
      ==> // number of vars : 2
      ==> //        block   1 : ordering dp
      ==> //                  : names    x y
      ==> //        block   2 : ordering C
        ring R2=Float(10,20),(a,b),dp;
        R2;
      ==> // coefficients: Float(10,20) considered as a field
      ==> // number of vars : 2
      ==> //        block   1 : ordering dp
      ==> //                  : names    a b
