Many thanks for your quick reply!

aaaahh so there is a tuper() construct! :) that helps a lot.. still this 
seems rather inefficient to create a list and then a new tuple.. but I 
guess there really is no easier way.

but is there a tuple=>list function ? so that instead of creating the list 
by a for-construct I could just say

list = tuple.tolist()
list[0] = newval
return turple(list)

?

-c.v.d.
