Great ideas -- thank you. The "r2" array in DO loop below is what I have been using. proc iml;
a = {2 4 6, 15 11 13, 29 28 27};
r1 = rank(a);
r2 = j(nrow(a), ncol(a), .);
do i = 1 to nrow(a);
r2[i,] = rank(a[i,]);
end;
print a ,, r1[l="Rank(a) - whole matrix - don't want"] ,, r2[l="Desired 'Row Ranks' from looping rank(row-by-row)"];
quit;
