Need Help??

Not obfuscated enough, it's still redable. Do not use -w.

for$x(1..26){my$r;$r=($x*$r+ord)%127
for"%E.g\cle(WW7=k\ct[bqI\abJy3.%\ctG"=~/./g;print chr$r}

Try using lots of punctuation variables for short japhs, separate operators from their operands, use funny math to hide constants, take advantage of aliases and default arguments. I like the idea you had on this one, so here it is a little less clearly: `map{$;=1?$?-$?:t;$;=($_$;+ord$&)%(2*7-$\|) while(qq]%E.g\cle(WW7=k\ct[bqI\abJy3.%\ctG] =~m>.>g);$..=chr$;}++$\|..26;s++$.+iii;print` [download] Brandan L.

A later japh using a similar idea: Polynomial JAPH. Update: see also my Japh algebra revisited. Update 2010-08-30: see also Fast Japh. Update 2010-10-03: see also ASCII arithmetic, Dollar Plus, Japh algebra, GF(128) edition. Update 2012-10-13: see also fft japh.	[reply]
