"        4th generation: usually proprietary languages that include FOCUS, the
                        language used by SAS Institute's products, etc. and
                        more recent languages like xBase (I'd classify APL as
                        4th generation -- these languages tended to have
                        reserved words that performed *huge* operations, like
                        statistical analyses, in one statement)

no, no, no! APL is definitely NOT a 4th generation language. Of the essence
in Jim Martin's notion of 4GL's is the idea of declarative languages
as opposed to imperative languages. APL is definitely an imperative language,
sure it is a very high level language (at least in some respects), but a
4GL is not simply a very high level language!
