If there is some interest in the early J interpreters, then people might like to know that there is some stuff on my website: a couple of zip files. Each one contains a complete set of source files from about 1993, a compiled executable, some documentation (read.me) and a build script Each executable (imp.exe or imp) is a single statically-linked file and should run in a terminal window.
www.learningj.com/W0.zip is for Windows: www.learningj.com/L0.zip is for Linux I have a copy of the "J Introduction and Dictionary", for Version 7 of 1993 and if there was any interest I could scan it and upload it (although I have an idea somebody might have done this already) Regards Roger On Fri, Mar 18, 2016 at 3:22 AM, Dan Bron <[email protected]> wrote: > Pepe wrote: > > Let us add another twist, courtesy of David Lambert, to the Exercise 1: > > > All these puzzles are interesting, but ever since you posted the “holy > grail”, the “write a tacit adverb to do X” challenges have been reduced (in > principle) to “write a tacit verb to do X”, and given you sent me, in > something like 2002, a complete implementation of a Turing Machine as a > tacit verb, the exercises seem … superfluous. > > In other words, it can all be done, because you have done all of it.
