   I am working on the generic External Method to do this. There is Zieve
Product for similar things.

   But if you want do it yourself (and I recommend to do it) - learn a bit
of Python.
   Sequence.sort() accepts a function, that does comparison, so you want
somethimng like this (untested):

def bmt_cmp(object1, object2):
   return cmp(object1.bobobase_modification_time(), object2.bobobase_modification_time())
      (note - bobobase_modification_time is a function!)

objlist.sort(bmt_cmp)
return objlist

           Programmers don't die, they just GOSUB without RETURN.
