Thank you very much for the suggestion to check 'mark' prior to calling either 'region-beginning' or 'region-end', as an alternative to testing the variable 'mark-active'.

> > In a custom test to determine whether the region is active, I had been testing mark-active prior to using (region-beginning) and/or (region-end) to avoid trowing an error "The mark is not set now, so there is no region".  When the following is true `(and mark-active (= (region-beginning) (region-end)))`, my custom function should return nil.

> Why can't you just check whether the function 'mark' returns nil?
