How to cull elements from a list using Formula

Whether it's because of ignorance or inexperience, I find that string and list handling are not completely covered in Formula language. I often find myself "inventing" functionality that would well defend a permanent place in Formula coding as a built-in function.

I offer to you a widget I sometimes use to cull elements from a list. I've dressed it up for testing. I would appreciate users testing this and responding with suggestions for improvements -- supposing that it is logically sound and fail-safe (I haven't really done that).

If this is already a built-in Formula feature, I haven't seen it thus far. But if it does already exist, I would appreciate any information you have about it.

the entire formula. Otherwise, all the displays truncate after a single entry.

I don't know if this only occurs on our Lotus Notes installation, but I find that in column formula and @prompts @Char(10) works, whereas @Newline usually doesn't.
