Somebody or other, I mention no names and I point no accusing finger, wrote, "Hmmmmmm...."
I ask you, what is the purpose and objective for that undefined comment?
In short my friends; Is it logical? Are we talking about implied Boolean logic which is used to represent Boolean logical operators, as the space between keywords defaults to either OR logic or AND logic. I would respectfully suggest the former as Boolean logic has become so common that it may be considered a de facto standard.
