Ak, js is passable, php? :)

This sort of hash table won't work anyway due to the 'word limitations 
of the current core

It will work with other keys, but has the same issue as 'select in 
that values can be mistaken for keys.

exactly  (or as the French say... exact)

Im tryin real hard to get my simple data into a Rebol hash table, 
or blocks.. whatever.. but it seems like traditional Relational DB 
is the way to go.. even used only as a flat file DB :(

; This may slow things down a little:

select-all: func [block [any-block!] key /locals result val fork][
    result: copy []
    parse block [
        any [
            thru key fork:

            (fork: pick [[set val skip (append result val)][]] even? index? fork)
            fork
        ]
    ]
    result
]

I'm a little confused... what word limit are you bumping into?  I 
thought the limit was

only for set-words?  Can't blocks have any number of symbols inside? 
 Until ram
is gone...

I guess the alternative is *sigh* waiting for R3 where these issues 
will be addressed...

terry is ordering your data when you insert it prohivitive?

sigh alright

somewhat tom

knowing more about how it will be accesses inser delete moce selecr 
would help choose a stratagey

if everytime you do a 'write' you need to sort 400mb file.. i would 
say yeah

Ok.. it's like this..

sorted keys you could binary seatch  to avoid linear scan

Terry;  Go back to the QRAM days, segment everything. :)  It only 
adds an order of
magnitude in complexity.  :)  Love Wintel...

Sorry.  I shut up now.

My data is structured using a semantic network model..  entites.. 
ie:

tweety   isa   canary
canary   isa  bird

bird   haspart   feathers
bird   haspart  beak

so you have seperate hashees of different relationship types

so currently its stored as entity - attribute - value  in a single 
db table using 3 cols

isa hash and partof hash

(lots of arguments out there regarding EAV as DB model...  most say 
it cant be done.. I say rubish.. works beautifully on a university 
project currently at 3 million rows of data)

it does work very well

It just seems that relation db is overkill   all i need is key/values 
 ... something like this.. 


n: [ tweety [ isa  "canary"  hascolor  "yellow"] canary [ isa "bird" 
haspart "beak"]]

I am wondering if you have a smallish number of relationship types 
 if splitting  into EA tables  getes you anything

the attributes are smallish

Brian, I believe words in blocks are limited as well

I do REBOL with pretty small datasets.  Could be  I just did a test 
of 1'020'000, but
I was inserting the same word with a number...not unique words.

yeah.. unique is the key  .. i need unique

Is there a need to maintain three columns, over say -- (bird [haspart 
feathers]) or (bird haspart/feathers)

(moving to DB Chat)

Brian, try -- repeat x 10000 [unless attempt [to-word join "w" x][break/return 
x]]

Warning: this will inhibit your ability to make new words in your 
console session.

any benchmark docs comparing certain functions with others?  ie: 
  foreach [ a b c ]  n..  vs   forskip n 3   ?

well, forskip is a mezzanine. you'd want fast loops to be done with 
natives like foreach

Joel Needly  et .al. used to bench mark all sorts of things on the 
mail list a few years back .tthe benchmarks would likely need to 
be redone with current versions of rebol

benchmarking: my site contains a very accurate block execution time 
measurement function

(and I have got a benchmark there measuring overall speed using a 
couple of algorithms - they are derived from a Byte benchmark published 
in june 1988) - we are quite a bit faster than the C language was 
on an average computer back then :-p)

btw, accurate measurement shows, that the high resolution timer is 
not very accurate

Ladislav - so we exchanged dynamic nature of language and sacrificed 
speed by doing the step 20 years back :-)

Ladislav;  I hope you don't mind, but I put a link to %timblk.r in 
a lot of the rebol.org
timing script documents.

Check http://www.rebol.org/cgi-bin/cgiwrap/rebol/documentation.r?script=timeit.r#toc-4
for a sample.

Any ideas on the best way to escape javascript as a Rebol string.. 

It's not uncommon to have double quotes, single quotes and curly 
braces in a single line  ie:


<a href="" onclick="$('mydiv').alpha({transparency:50%});"> Fade</a>

FYI .. built a block with 1 million  (random 1000000) integers then 
ran a forskip myblock 3   vs  foreach[ a b c ] myblock
forskip time:  0:00:02.828
foreach time: 0:00:00.046

time the while loop while you are at it (db chat sat 8:58)

closer to the forskip time I would imagine

and a parse-rule.

Terry, the reason is foreach is native and forskip is a somewhat 
heavier mezzanine which calls WHILE to do its work. See Henrik's 
comment above.

Can't you just put curly braces around the string Terry?

um I can ;)   didnt' realize you could nest curly braces
