Upon further investigation of this "language", I have decided that the fellow in question is quite assuredly insane. Not to mention he has some rather .. fascinating concepts of life and social order. I spent 15min on his website - and want it back :P

I must have spent the amount of time there too. Weird or wonderful? 15 minutes wasn't enough to decide. But think of the application to stenography. Entirely applications could be embedded in their installation manual. What do you get if you execute (if you see what I mean) Hamlet? On the other hand, DNA works with just four letters. ETA looks bloated in comparison, <g> Sunanda.

Yeah, I was just thinking that eta looks a great language for self-modifying genetic algorithms... Absolutely insane language to try and use for real though, makes even obfuscated perl look readable! :) Chris -- .------{ http://www.starforge.co.uk }-----. .--------------------------. =[ Explorer2260, Designer and Coder \=\ P: TexMaker, ROACH, site \ =[___You_will_obey_your_corporate_masters___]==[ Stack: EETmTmTRRSS------ ]

An other 8-commands language ist brainfuck. http://www.muppetlabs.com/~breadbox/bf/ Only the characters [],.+-<> are used. Example-Implementation:

>> do http://proton.cl-ki.uni-osnabrueck.de/REBOL/brainfuck.r >> brainfuck/program

== {[ >++++ [<++++++++>-] <.,]}

>> brainfuck/run "HELLO^@"

== {hello}

>> brainfuck/program: {>,[>,]<[.<]}

== ">,[>,]<[.<]"

>> brainfuck/run "Hello^@"

== "olleH" And it can make rebol-functions out of the brainfuc-programs:

>> a: brainfuck/rebol-func >> a "Hello^@"

== "olleH" I tried to use this implementation for genetic algorithms. I was able to learn some simple programs like "reverse" "uppercase" etc. Have fun Frank

Looks a lot more "application oriented" than pure lambda calculus, Turing machines, Markov Normal Algorithms, etc. ;-) I took the whole thing as a hilarious geek joke (especially the base-7 part...) -jn- -- Future looks spotty.

Or for those who have trouble with remembering too many different instructions, try languages with just one instruction: http://www.hawaga.org.uk/text/oisc1.html Sunanda

Gee, that would make our job easy!

The instruction would be: throwException

Gentlefolk, for the benefit of those of us behind corporate content filters (eg. InterScan eManager Content Management Notification! (Offensive Language)), could you please refrain from using the f word (or like terminology). Having to search Escribe for blocked content is a real pain ;) Regards, Ashley

Thanks for the implementation!
