If you don't have very large data then you can perform a Cartesian product and write a logic to count.

data a;
infile cards missover;
input a b;
cards;
0.1 1
0.2 2
1   3
1   4
2   5
3   6
4
4
;
run;

proc sql;
create table many as
select t1.b,t2.a
from a as t1,a as t2
where t1.b is not null
order by t1.b
;
quit;
data want(drop=a);
retain count;
set many;
by b;
if first.b then count=0;
If b-1<a<=b then count+1;
if last.b;
run;

If your data is large I suggest Hash table method.

some more clear on want I want thanks alot everyone ..but I need like B column value need to search for same and less then to A column value.. if it taken a count from A column it doesn't repeat count when it taken a new value in column B....example

I'm showing how it on small data to make clear...

a b

1.1 1

1.2 2
1.3 3

2.1

2.2

Require output:

b c

1 0

2 4

3 1

Are you after this????

Your wrote --" I need like B column value need to search for same and less then to A column value."

Require output:

b c

1 0

2 4

3 1 /*this should be 7?*/

data a;
input a b;
cards;
0.1 1
0.2 2
1   3

In the below which you written code the count gives as

b count

1 4

2 5

3 6

4 8

5 8

6 8

b count

1 4

2 1

3 1

4 2

5 0

6 0

In this way needed ... if a value is counted when it less then or equal to.. it should not repeat count again....

Since both columns a and b are sorted, you can take advantage of that fact as below:

data a;
infile datalines missover;
input a b;
cards;
0.1 1
0.2 2
1   3
1   4
2   5
3   6
4
4
run;

data want ;
  do c=0 by 1 until (inb);
    set a (keep=a rename=(a=b) in=ina)
        a (keep=b where=(b^=.) in=inb);
    by b;
  end;
run;

data a;
input _a b;
a=ceil(_a);

Thanks everyone I have applied above code from the following data but count not getting.. can some one check

Required output:

count

6 ---less then or equal to 0.00288

18----less then or equal to 0.00381

and so on.....
