Common Lisp, of course, has built in hash tables. MacLisp doesn't seem to - I didn't see anything about them in the Pitmanual. ZetaLisp/LML and InterLisp have them. So it seems like built in lisp associative arrays (I'm not counting alists, or property lists, though the latter goes back to the early days and maybe should be) are roughly contemporary to the birth of awk. Maybe a bit newer.
