I set up some crude code that gets your intended result, but I made all variables in test numeric:

data test;
input n x y;
datalines;
1    13    18
2    15    8
3    6    13
4    7    14
5    9    5
6    11    6
7    12    7
8    14    9
9    18    11
10    19    12
11    3    20
12    4    19
13    17    3
14    2    4
;
run;

data second;
set test (keep=y n rename=(n=n2));
n1 = _n_;
x = y;
run;

proc sort data=test;
by x;
run;

proc sort data=second;
by x;
run;

data
  third (drop=n1 n2)
  nomatch_t (drop = n1 n2 y)
  nomatch_s (drop = n n1 x rename=(n2=n))
;
merge
  test (in=a)
  second (in=b)
;
by x;
if a and b then output third;
else if not b then output nomatch_t;
else output nomatch_s;
run;

proc sort data=third;
by n;
run;

proc sort data=nomatch_t;
by n;
run;

proc sort data=nomatch_s;
by n;
run;

data fourth;
merge
  nomatch_t
  nomatch_s (drop=n)
;
run;

data want;
set
  third
  fourth
