Hello,      I'm trying to iterate through a dataset for a specific set of rows (say 5), so for the first observation when it is read it has to read through the next 4 rows. So when we read the second observation it has to loop through 3,4,5,6 rows and for third obs read through rows 4-7 & so on... When it comes to the bottom rows it should read what is left over. Like in row 10, it can read only 11  & 12.    Is there a way to achieve this through retain statements or array?   the dataset might look like below: DSet : A ID    Date    Cost 1      8/1/2020       100 2      8/2/2020        230 3      8/3/2020        450 4      8/4/2020        660 5      8/5/2020        670 6      8/6/2020        230 7      8/7/2020        420 8      8/8/2020        110 9      8/9/2020        430 10    8/10/2020      140 11    8/11/2020      180 12    8/12/2020      340 ...
