Being a fully-fledged member of the pedants' society, I can't let that go without comment. Those dates only hold if you stick to FORTRAN. Algol-68 had if-elif-else-fi, and I don't believe it was a pioneer in the structure even then (although the syntax may have been novel). It also had a case-esac structure. I'd say both elseif and case/switch developed in other languages and were adopted into FORTRAN long after they were established as bona fide programming constructs. Cheers!
