Quite right... it embarrasses me too. But unlike Vista, there *is* a market for historical reprints. Especially in the APL world. The original brief was to issue a collection of reprints of Gene's landmark papers. We've delivered on that -- and you can buy the book. (And people have.) But then it was pointed out that here we have an all-too-rare collection of original mathematical research which actually shows the thought-processes towards getting there... and with free software available to run the examples. Let me stress that what's on the stocks is not a book for people who want to learn J but a book for people who don't want to learn J. (At least not at the outset.) But then, of course, the examples must work. With J straight out the box. All of them... not the 96% of Edn 1 (with deprecated features enabled.) All I can say right now is... watch this space. (BTW: Nobody's calling yet for a version of Ken's "A Programming Language" which runs faultlessly under Dyalog 12.0... but wouldn't it be nice if all vendors could issue releases for people who don't want to run Vista!)
