Ah, the 'or' operator does it. Thank you, that is exactly what I was
looking for.

I should confess, I am not a programmer and don't even know what
"idiomatic" means in this context. I don't know Java or PHP, only a
little Forth from the HP calculator era. Advanced topics I just skip
over because I don't understand them. But I am learning slowly and
appreciate the help.
