GT - LT WITH DATES?

[Raffe, Sydelle, SSA]

I recall being able to use operators like gt and lt with vars in date format. But, nothing happens. Can someone set me straight? Thanks.

You may have to use a date function as part of the logical evaluation, something like this:
 
DO IF (birthdate GT (DATE.MDY(12,13,2000))).
COMPUTE x = 1.
ELSE IF (birthdate LT (DATE.MDY(12,12,2000))).
COMPUTE x = 0.
END IF.
 
Of course, we could simplify the command to be:
 
COMPUTE x = (birthdate GT (DATE.MDY(12,13,2000))).
 
.. and that should do the same thing.
