What's the meaning of (+)?

Hi all!

What's the meaning of a "(+)" after a comparison in a WHERE statement?

SELECT p.PNR, k.KIND
FROM PERSONAL p, KIND k
WHERE p.pnr = k.PNR(+) AND p.PNR < 130

I've just stumbled across it in the exam preparations, but I can't find it documented somewhere in my papers.

Thanks for helping!

PS: PERSONAL is PERSONELL or EMPLOYEES, KIND is CHILD
