Greetings, Just providing some feedback....
The fist thing I wanted to know when I started J was how to exit. I did some research and discovered 2!:55. I then defined a verb and used that to exit. Therefore, in order to get a clean way to exit a new language, I had to learn what a verb is, what system verbs were available, how to define it, and how to load it. (I know about ^d but think that is hardly a clean way to exit.) Now, years later, I discover the pre-defined verb 'exit'. I checked the docs, especially "Learning J". There is no mention of 'exit'! As someone who has played with many languages over the years, and in fact an author of one, I respectfully suggest updating chapter 1 of Learning J to tell the user how to exit. Making a research project out of the first obvious desire is an unnecessary impediment to a language acquision. Additionally, since I discovered 'exit', a comprehensive dictionary of pre-defined verbs would be very helpful. (I know about z, etc.) Thanks. Just some thoughts...
