Yay! 2nd place! I guess I can be proud of it still.

Look Ma, 4 iif()'s. \:\)
What have you done, silly Boy! *Slap*



for 247:
 Code:
function a($, optional $k)
    dim $e,$m
    $k=$k+$<' '
    $m=' ','	'
    $e=$<!
    while $
        dim $c,$n,$x
        $x=asc($)
        $n=128
        while $n
            $c=$c+iif($e,$n*(($k^$<' ')&$>),$m[$k^$x/$n])
            $x=$x-$n*($x/$n)
            $n=$n/2
            $=iif($e|$n=0,right($,~),$)
        loop
        $a=$a+iif($e,chr($c),$c+iif($,@,$m[$k]))
endfunction

The way you are using $k has me completely vexed. Wicked code indeed.

I'm really looking forward to seeing the others now.

ok, sorry guys, haven't been around to post my code.
here is my 173:
 Code:
function a($t, optional $k,$,$b) 
 $a=$k
 if $t
  $a=chr(iif($k,9+($k=" " ^ ($ & asc($t))>)*23,($=)*$b))+a(substr($t,2-(~$ & $k)),$k,$/2+64*($=),$*(right($t,1)<>left($t,1))+$/$*$b)
endfunction

Howard,

Nice one.
I wonder why I haven't seen that \:\(

Oh sure, Jooel did what I thought was impossible due to mix of integer and string values. So clear that he must have found a way, but couldn't come up with something.. Sure must run out of spare souls \:o

integer values?
what you are talking about?

what wondered me was how many lines you guys had.
I don't remember having that many even in my very first code. \:\)

oh, and here is my last code at 181 that supported 8bit characters (you know, , , etc...):
 Code:
function a($t, optional $k,$,$b) 
$=$+128*($=)
$a=$k

if $t
 $a=chr(iif($k,9+23*($k=" " ^ ($ & asc($t))>),$/99*$b))+a(substr($t,2-($>1 & $k)),$k,$/2,$*(right($t,1)<>left($t,1))+$b*($<99))
endfunction

you know .. while decoding: asc($) is an integer ;\) in opposite to space or tab while encoding.
I tried to do it recursively too but that didn't shorten the already gridlocked code. Should have follow this approach from the beginning or start compeletely over.

howard, or someone, can you check that you posted your working code?
I got this out of your 255:
 Code:
KiXtart Version  = 4.61
KiXGolf Script   = kixgolf_wo.kix
Scoring Engine   = 3.3
OS               = Windows 7 Professional Edition
CPU              = Intel Pentium III
Speed            = 1396 MHz
Memory           = 4096 MB

Tournament       = Whitespace Obfuscation
Processing Start = 2011/11/14 12:48:56.692
Processing End   = 2011/11/14 12:48:57.157
Duration         = 0000/00/00 00:00:00.464
# Tests Run      = 40
# Tests Passed   = 30
# Tests Failed   = 10
Result           = Failed
KiXGolf Score    = 255

wtf... also your edit of jochen's code produces this:
 Code:
KiXtart Version  = 4.61
KiXGolf Script   = kixgolf_wo.kix
Scoring Engine   = 3.3
OS               = Windows 7 Professional Edition
CPU              = Intel Pentium III
Speed            = 1396 MHz
Memory           = 4096 MB

Tournament       = Whitespace Obfuscation
Processing Start = 2011/11/14 12:51:09.323
Processing End   = 2011/11/14 12:51:10.042
Duration         = 0000/00/00 00:00:00.719
# Tests Run      = 40
# Tests Passed   = 20
# Tests Failed   = 20
Result           = Failed
KiXGolf Score    = 246


what is going on? am I going crazy?

this is indeed crazy.
took jochen's code. it worked.
removed the first dim, got this:
 Code:
function a($, optional $k, $e, $m)
    $k=$k+$<' '
    $m=' ','	'
    $e=$<!
    while $
        dim $c,$n,$x
        $x=asc($)
        $n=128
        while $n
            $c=$c+iif($e,$n*(($k^$<' ')&$>),$m[$k^$x/$n])
            $x=$x-$n*($x/$n)
            $n=$n/2
            $=iif($e|$n=0,right($,~),$)
        loop
        $a=$a+iif($e,chr($c),$c+iif($,@,$m[$k]))
endfunction


tested, it works.
it's 245.
compared with what howard had, exact same look.
replaced with howards code and again it failed with 246.
I am not seeing the light here!!!

found it.
howards code from jochen's does not have tab in it -> fail.
hmm... that means I ended up with that 245 score? \:o

lol, as stated in private: Got to teach your editors not to replace tabs with spaces (unless using notepad or something)

edit: checked Howards post, and indeed the tab in $m='[space]','[tab]' is replaced with two space characters. Ohnoes \:o
