Is there a was to create a count/sequence var to +1 when encountering a '1'? For example, if I had data that looks like this, I do not want to change any sort order, I just want to increase count +1 every time it encounters a 1; Help is appreciated!
Have | Want ORD 2 |
1 | 1 |
2 | 1 |
3 | 1 |
4 | 1 |
5 | 1 |
1 | 2 |
27 | 2 |
28 | 2 |
29 | 2 |
30 | 2 |
1 | 3 |
37 | 3 |
38 | 3 |
39 | 3 |
40 | 3 |
1 | 4 |

Hi @jenim514 Methinks all you need is
if num=1 then want+1;
data have;
input num;
datalines;
1

if num=1 then want+1;
