complexlist =
    Table[Random[Integer, {-100, 100}] +
        I Random[Integer, {-100, 100}], {50}];

Sort[complexlist, Re[#1] < Re[#2] ||
    (Re[#1] == Re[#2] && Im[#1] < Im[#2]) & ] // TableForm

Hi, I need some help
  I am trying to sort a list of complext number, say, List={a+b*I, c+d*I};
 and I want a>c and b>d. I know that Sort can do this with a small list of
complex numbers, but what I deal with is a list of about 100000 and maybe
more, and it doesn't seem to work with the imaginary part when you just
Sort[List],
 Does anyone have a small program to do this?
 thank you
