I need a way to define if a group (for example named "test") is empty or not.
I found a way to handle not-empty groups, but there are problems when they are empty:
(command "_.select" "_group" "test" "")
; -> returns always nil for empty and not-empty groups
(setq aws (ssget "_P"))
;-> Problem: "_P" are the elements of the not-empty group OR (if empty) some other "previous seöections"
I'm sure that there is a simple way which someone can show me ...
