Hi,
If you have declared the user defined type (udt) to be 'self as ref' e.g.
create type testo as (val_int int) *self as ref*;
create type testi as (val_o testo);
then the assignments as :
self.val_o := new testo ();
self.val_o.val_int := x;
must work.
As for array[x][y] := val; this must be working too, in which case it
doesn't ?
Best Regards,
Mitko
