I don't know why it doesn't accept it but, at risk of being condemed for
suggesting a "goto" solution, you could accomplish the same thing with:

proc iml;
do c = 1 to 5;
 if c < 2 then goto NextOne;
  do g = 1 to 2;
    do n = 1 to 5;
     chance = ranuni(0);
     print chance;
    end;
  end;
NextOne: end;
