I am trying to calculate age of patients it gives 'type mismatch
error' (r(109)) for both of the following commands:
gen momage=scrndte-dobmom
and
gen momage=(scrndte-dobmom)/365.25

Apparently at least one of the variables -scrndte- and -dobmom-
is a string variable, so subtraction is an illegal action.
You can see the variable type by -descriptives-.
Hope this helps
