Hi! I think there is a problem of updating the documentation. For example, in Primer - in tacit definition, still some x. and y. - in tacit definition, at the end the discussion doesn't agree with the screen captures - the file system was modified in 6.02, but this is not in Primer, where some examples do not work (especially the "user" folder, problem with profile.ijs???) - for component files "jsize f" returns 2176 and not 1408 - the two GUI exercises give error with "wd"
I know that maintaining documentation is almost as difficult as maintaining the program itself, but if we want to have beginners use J, the documentation should be straightforward. One has not to expect that the user will correct the mistakes, he will just go and use something else. And what about the other books; User's manual, Introduction and dictionary, Exploring math,...? I have just received Vector 24/1. They announce the book "At Play with J", but immediately say that there will be a second revised edition "in which the examples match the current version of J". Would you start using any program in that conditions? Alain Delmotte Brian Schott a écrit : > Don, > > Your fix helped, but I have another question.
