Kim,

If you initialize a seed vector and pass that vector to the
ranbin function, then you get a vector of pseudo-random variates.
The code

   proc iml;
    seed = J(8,1,1234579);
    y = ranbin(seed,1,0.5);
    print y;
  quit;

returns the vector Y with values shown below.

      1
      0
      1
      0
      0
      0
      1
      0
