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!
