In the new part of documentation (from v0.9 build 10 of analysis) there is a file with "how to ..." on this topic the content is:

Select by date - existing variable Solution: use the built in formulae. Adapt according to your date format (dmy/mdy/ymd)

E.g. to select all born before 12th of february 1988:

Select birthday < dmy(12,2,1988) Select birthday < date("02/12/1988","mdy") Select birthday < date("12/02/1988","dmy")

The first uses function dmy(,,), the second date(,) with mdy and the third date(,) with "dmy".
