I think so. Here's some tricks with associate -- decide for yourself :-) myAA: copy [] ;; start a new associative array associate myAA 'today now associate myAA 'myname 'Sunanda associate myAA 'my age 21 ;; It was once. Then again later in hex..... associate myAA 1-jan-2000 {new millennium} associate myAA 15 [4 5 6] [1 2 3 4 5] ;; ways to sum 15 as consecutive integers ;; read some of them back: associate? myAA 15 == [4 5 6] [1 2 3 4 5] associate? myAA 'today == 3-Jan-2005/22:17:39 ;; well, it was when I did it -- it's a static value ;; let's get a date that really does update itself: associate myAA 'today [(now)] compose associate? myAA 'today ;; result will change each time ;; being just a rebol block, I can write it to a file, and reload it later write %myAA-file mold myAA myAA: none ;; to prove it's gone myAA: load %myAA-file associate? myAA 15 == [4 5 6] [1 2 3 4 5] ;; same values as before I could add the whole thing to another associate array my-other-AA: copy [] associate my-other-AA 'AA1 myAA ;; I could even add it to itself: associate myAA 'myAA myAA |
