Hi there,
I wonder if someone can help me to figure it out of how to write code for filling the consecutive values, as following:
ID | VISIT | VALUE | WANTS |
A | 1 | 0 | 0 |
A | 2 | 0 | 0 |
A | 3 | 1 | 1 |
A | 4 | 0 | 1 |
A | 5 | 0 | 1 |
B | 1 | 0 | 0 |
B | 2 | 0 | 0 |
B | 3 | 1 | 1 |
B | 4 | 0 | 1 |
B | 5 | 0 | 1 |
for example:
ID A at visit 3, the value = 1, I want to fill the consecutive visits with the value as 1.
Please let me know if my question is not clear enough.
Thanks you very much in advance.
BY-processing is perfect for this type of problem:
data want;
retain WANTS;
set have; by ID;
if first.ID then WANTS = 0;
if value then WANTS = 1;
run;
Edited, thanks to ballardw!

If Value then Wants=1;
I think.
Thanks, ballardw for updating the code.
I appreciate your help!
wow, it works!!
Thanks so much!!
