But it's too big and too powerful to teach real programming. To fully understand computers one must be forced to program at no higher than machine language and have to handle the most basic level of hardware I/O, optionally aided by an assembler. Wouldn't hurt to have to do a little microcoding as well. FORTRAN and above are not really programming computers, but programming virtual machines which hide most of the true aspects of computers. It's the difference between an automobile driver and an auto mechanic. And those who only build WEB pages are only riding the bus.
APL and J almost completely remove the physical characteristics of computers and are more of mathematical virtual machines. As such I don't think of writing J as programming a computer, but programming mathematics. And maybe APL and J are riding the bus also, but a really fancy bus. Oh! And who is going to be the first to put J on this little beasty?
