You *could* use

function data::add,data2

;; common code

if OBJ_CLASS(self) eq 'DATA' then begin

;; do everything for DATA ADD

endif else begin

;; do everything for TIMEDATA ADD

endelse

end

But this is goes again the concept of inheritance. Overloading ADD is
the much cleaner
way. Instead you should factorize you code, ie. define a
DATA::ADD_COMMON and put in there everything both ADD functions share
and
call it from both ADD functions leaving only the differnces there.

Cheers,
marc
