Dear all; a beginner question How can I create a loop that will select the data for five minute intervals... Basically, I want the program to choose the five minutes intervals between 1530 and 22:00. Said differently, I would like the program to choose 15:30-15:35, 15:35-15:40 ,so forth untl 22:00,,, then within that loop I would like to make calculations for the subset,...then output them, also for each interval, is it possible to use the proc procedures like proc mean, proc reg, etc thanks Sony
