I am working on a code to group date ranges and create a dummy variable and I am stuck trying to figure out why SAS is not picking up on the code. I would like to know if I am heading in the right direction.   DATA work.import; SET work.import; IF (eventdate >= "03012020") and (eventdate <= "03312020") then month = 3; IF (eventdate >= "04012020") AND (eventdate <= "04302020") then month = 4; IF (eventdate >= "05012020") and (eventdate <= "05312020") then month = 5; if (eventdate >= "06012020") and (eventdate <= "06302020") then month=6; if (eventdate >= "07012020") and (eventdate <= "07312020") then month=7; if (eventdate => "08012020") and (eventdate <= "08312020") then month=8; if (eventdate => "09012020") and (eventdate <= "09302020") then month=9; if (eventdate => "10012020") and (eventdate <= "10312020") then month=10; if (eventdate => "11012020") and (eventdate <= "11302020") then month=11; ...
