Another nonstandard form is "Without p, then q."
"Without distribution requirements, most students would take too
narrow a range of courses."
Here we do not have two component propositions; the phrase
beginning, "without" does not contain a whole statement. Yet
it is easy to turn that phrase into a whole statement: "If
distribution requirements did not exist, most students would take
too narrow a range of courses."
In general, "Without p, q" can be translated as, "If p does not exist
(or occur), then q."
