Dear Guy, I certainly agree with the sentiment of your email subject line. Thank you for including me in your proposal. One attempt made to broaden the appeal of APL was to write an introductory APL tutorial, along the lines of Ken Iverson’s Working Introduction, but which can be copied and distributed freely, albeit sadly without a CD containing an interpreter to match the course. In my life at IPSA in London in the 19980’s I was fortunate to attend the Working Introduction to APL and also the Working Introduction for Instructors, both given by Ken. In the attached third edition course notes I have attempted to single out the particular characteristics of elementary APL that make it so attractive for us, and to describe these characteristics in terms that Ken Iverson himself might have approved of. Well.., maybe not entirely. ;-) I have also written a second free course which Ken might well have enjoyed tearing into shreds. It explores the rationality and scope of Dyalog APL, specifically. Download: http://robertson.uk.net/files/apl3&4.pdf This offering is more critical and more controversial than the first, but it does provide a welcome signpost to the hearts of many specifically Dyalog features and extensions to the language. This course is a most efficient way of learning the ins and outs of Dyalog APL to some significant depth. It is the result of 10 years as the APL Consultant at Dyadic, sharing an office with the developers throughout. It contains a lot of material in condensed form and clearly needs a working Dyalog APL interpreter to get the real benefit. Of the first book, Waterstones bookshop (Peter North) said that the cover and other elements were not suitable. Of the second book, Waterstones said that the cover was better (but still didn’t look too good). I have sold a few on Amazon and I believe that the second edition, APL1_2.PDF, has been a popular download from the MicroAPL web site since 2004. I hope YOU can find an inspirational way to convey APL thinking to lots of existing programmers and potential programmers. Kind regards, Graeme Robertson, BSc MLitt PhD. " address@hidden From: LaRocque, Guy (NRCan/RNCan) [mailto:address@hidden Dear colleagues, You are receiving this email because you are a member of the steering committee of an association or belong to the community of developers or consultants of a programming language derived from Iverson’s mathematical notation, including APL, J, K, A+, Nial or Gauss. Recently, I had a discussion with APL colleagues about the international visibility of these different array programming languages. We are aware of the fact that the majority of associations, developers and consultants have good web sites with a lot of good information, but our impression is that there is a lack of good communications among the different associations in different parts of the world. The reason I am sending you this email is to suggest the idea of forming an informal international group that will improve communications among the organizations and users of languages derived from Iverson’s mathematical notation. This international group could (1) establish linkages between the web sites of the different associations, developers or consultants, (2) organize webinars, (3) assemble lists of users across the world, and (4) provide efficient means of internet communications among organizations and users. The objective of this idea is not to create a “super” organization that will consider existing groups as affiliates, but simply to promote good communications and improve the visibility and use of the different languages. If you like the idea and wish to initiate discussions, please, let me know.
