How to create a weekday/weekend indicator variable based on date?

[sasgorilla]

As the subject says, I'm trying to figure out how to create a weekend/weekday indicator variable based on date. 

I have found the weekday. format where Sunday =1, Monday =2, etc. and am trying to use a statement in a datastep such as: 

If (weekday format of my date) in (1 7) then weekend = 1;

ELSE IF (weekday format of my date) in (2:6) then weekend = 0;

I'm having trouble figuring out how to indicate (weekday format of my date). 

Thank you for your help!

Instead of looking at the weekday format, look at the weekday function.  It can easily be plugged into your existing code.

Thank you! The function did the trick. 

IF weekday(date_of_Injury) in (1 7) then weekend=1;
	ELSE IF weekday(date_of_Injury) in (2:6) then weekend=0;
