J-Learn -- Students of array-programming language J
About J-Learn	English (USA)
J-Learn: a mailing list for some students of algebraic array-processing language J Members are invited to post questions, insights, and small examples for the others to consider. Membership requests and postings from "outsiders" will go to the moderator for decision. Moderator/Instructor is Arthur Anger of Concord, Massachusetts, USA, who hopes to read postings about once per day, and offer comments when it seems suitable. I do not expect telephone consultations to be very fruitful. To get started, visit http://www.JSoftware.Com to download and install a free J-system appropriate to your computer's operating system. (Select the "stable" option. Unless your Windows system is very new, with "64-bit" all over the documentation, select the "32-bit" download.) You are not required to supply any personal information or identification to obtain or operate the system, but you may join one or two (other) E-mail forums (via a J-wiki button), to read what other people are doing with J and what they have to ask or tell about it. After starting J, press F1 or select Vocabulary under the Help menu. Your browser should open a page listing nearly all of the fundamental symbol meanings in J. The top and bottom menus within the page offer access to a Primer, "Learning J", a Phrasebook, other components of the Dictionary, and an Index. The Studio menu offers Demonstration programs and tutorial Laboratories. The website wiki pages list relevant printed texts which you can order. To see the collection of prior postings to the list, visit the J-Learn Archives.
