I don't think that is the same problem at all.

Ronnie's code -list-s observations if any of the -other?c-
is over 22 (but not missing).

Ulrich's code -list-s them only if all of the -other?c-
are over 22 (and none of them are missing).
That is much more restrictive.

In addition to my earlier suggestion, -egenmore- on SSS includes
function -rany()-, -rall()- and -rcount()-.
