[REBOL] hash Re:
-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, April 14, 2000 11:57 AM To: [EMAIL PROTECTED] Subject: [REBOL] hash is there anybody who can explain me hash value. what it is used for, how it works etc. Hi, as I understand it, the datatype is just like a block from a functional point of view but supports fast lookup for key/value pairs. So if you have an even number of key/value pairs inside a hash! and use find, it will use a binary-tree search approach, much faster than a sequential search through the block. Hope this helps...

Hmmm... this seems a bit crazy to me... ;-) What about:
if all [C #"A" C #"Z"] [ ... ]
Anyway, with parse:
upper: charset [#"A" - #"Z"]
== make bitset! #{
FE07
}
line: "ThisIsTheLine"
== "ThisIsTheLine"
parse line [skip some [here: upper (insert here " ") skip | skip]]
== true
line
== "This Is The Line"

And seeing as I was in a rush (a bad state for writing software in...), and my tools made my solution easy to write, I sent it out. Of course, this is a more accurate test: all [#"A" = C C = #"Z"] ;-) Andrew Martin Tools triumphing over good design... :-( ICQ: 26227169 http://members.xoom.com/AndrewMartin/ --

Hi Ryan, you wrote: Original (with three urls in the block) adnumber - 1 * 3 random (length? banner-db) / 3 make-banner/ad 3] My changes (with six urls in the block) adnumber - 1 * 6 random (length? banner-db) / 6 make-banner/ad 6] The 3 in adnumber - 1 * 3, that 3 does not stand for number of entries in the database. It stands for the length of a database entry, i.e. each entry in the database consists of three items: http://www.schonder.com %/graphics/bannerads/schonder.gif "Papier-Schonder KG office supply and bookstore" 1. the url: http://www.schonder.com 2. the banner file: %/graphics/bannerads/schonder.gif 3. the accomapnying text: "Papier-Schonder KG office supply and bookstore" You added 3 more companies, fine, you therefotr changed 3 to 6 in your call to make-banner/ad 6, that's fine, but you now have 18 entries in the database, six records of length 3 each, and not 36 entries. But when you call make-banner with the ad refinement, get adnumber - 1 * 6 is 6 - 1 * 6 = 30. No wonder you get none. ;- Elan [: - )]
