initial

ab2=a2*b2;
end

always @ (posedge clk or negedge reset)
begin
if (reset == 1'b0)
begin
end
else
begin
ve[0]<= x*ve[0] + ab1*(p[0]-a[0]);
ve[1]<= x*ve[1] + ab1*(p[1]-a[1]);
ve[2]<= x*ve[2] + ab1*(p[2]-a[2]);
ve[3]<= x*ve[3] + ab1*(p[3]-a[3]);
ve[4]<= x*ve[4] + ab1*(p[4]-a[4]);
end

end
endmodule

I given code above. ' V ' variable it is a inout port because the previous value is given as input and the new value is calculated and then stored in the same variable. As the inout port should be a wire. the calculation is done in behavioral block with a temporary register ' ve '. but including the assign statement to update V introduces the error mentioned.
