[REBOL] Multidimensional arrays ...

[Petr . Krenzelok]

Could anyone elaborate on following, please?

->> ar: array/initial [3 4] copy ""
== [["" "" "" ""] ["" "" "" ""] ["" "" "" ""]]
->>  change ar/1/1 "adfaf"
== ""
->> ar
== [["adfaf" "adfaf" "adfaf" "adfaf"] ["adfaf" "adfaf" "adfaf" "adfaf"]
["adfaf" "adfaf" "adfaf" "adfaf"]]

How to simply write at any multidimensional array position? ar/:i/:j:
value doesn't work ...

Thanks,
