is there a nicer way to define an empty list (no elements) with @formula language instead of the following:
list:= “”;
list:=@Subset(list;@Member(“”;list)-@Elements(list));
Subject: Just curious, why do you write it that way ?
list := @Subset(“”:“”; 0)
That is essentially what your original code is doing, right ?
Subject: The second argument to @Subset must not be zero.

Subject: list := “” is sufficient
I suppose you are seeking for something like an empty array, i.e. no elements strictly speaking. I’m afraid that concept does not exist in the Notes formula language, just like there is no such thing as a truly empty field on a Notes document. The closest approximation you can get is an empty string.
Subject: What are you actually trying to do?
My guess is you’re using this null/empty list for something. It might help if you described what you’re trying to accomplish; perhaps there’s another way to skin that cat and we can provide some input into a solution.
