I would like to create an age variable that subtracts
each dob from a particular date. I looked at the
reference guides and web page, but they were not
helpful in answering this question.
I've tried the following, but they both create missing values.

generate age=mdy(4,15,01-dob)/365.25
The "year" part of mdy has domain 100 to 9999, and should probably be something like 2001 - (year of birth). In both you examplese the year you provide is less than 100 and not valid (see documentation of mdy).
