Hi Andrew, Here's my latest attempt. make-hash: func [][ make object! [ pos: none keys: make hash! 1000 values: make block! 1000 set: func [key value][ either pos: find keys key [poke values index? pos value] [append keys key append values value] ] get: func [key][ either pos: find keys key [pick values index? pos][none] ] ] ]
>> a: make-hash >> a/set "brown" "chairo"
== ["chairo"]
>> a/set "green" "midori"
== ["chairo" "midori"]
>> a/set "brown" "kogechairo"
== ["kogechairo" "midori"]
>> a/get "brown"
== "kogechairo"
>> a/get "midori"
== none Still, all the experimenting I've done indicates Rebol can't do large associative arrays (more than a couple thousand keys) nearly as efficiently as Perl. Eric
