The British APL Association (BAA; infrequently BAPLA) is a user group founded in 1984 in England to promote APL, and the publisher of Vector journal. It is funded by its sustaining members, which include corporate users and the APL vendors APL2000, Dyalog Ltd., Kx Systems, and MicroAPL.

The BAA was a Specialist Group of the British Computer Society from its early years (possibly beginning after APL86[1]) until it left in response to increasing requirements made by the BCS in 2008.[2]

Vector journal

Vector, the journal of the BAA, began publication in 1984, and gradually took the place of APL Quote Quad as the de-facto leading publishing channel for APL content. The journal featured submitted articles on array programming including J and K, as well as news from APL and other array language vendors. Beginning in 2005, with volume 21 issue 4, the journal was issued online as well as in print, and some prior articles have also been made available online.[3] It was published quarterly until 2004, when late and sometimes skipped issues began to interrupt its formerly regular schedule. Releases slowed more significantly after 2008, and in 2016, following the completion of volume 26, the journal moved entirely to online publishing. So far a single issue has been published this way, in 2019.

Regular meetings

Symposium

From 2008 and until the onset of the COVID-19 pandemic, the BAA London group arranged a monthly open-for-all meet-up, called the symposium, at the The Hoop and Grapes pub on Farringdon Street in London. No sign-up was required.

Webinar

Main article: BAA Webinar

BAA began a series of webcasts in 2020. Initially oriented around a presentation on a particular topic, most meetings are now open sessions without any planned topic. Participants are still encouraged to present or raise any subject, and can request in advance that an episode is set aside for such.

The events are held at 16:00 UK time, every other Thursday on even-numbered ISO weeks. The current week number can easily be determined using Dyalog APL: ⍬2⊃¯11⎕DT'Z' gives 9 this week.

BAA webinars are held using Zoom:

Individual events

Conferences

APL-ication was held 28th-30th September 1988 at the University of Kent.[4]

The two-day conference BAPLA 09 was held on June 8th & 9th 2009 at DeVere Hotel, Wokefield Park, near Reading, UK.

Iverson Centenary

On 17 December 2020, a special webinar was arranged to celebrate the 100th anniversary of the birth of Ken Iverson. Around 200 attendees from around the world attended as the panel consisting of Roger Hui, Leslie Goldsmith, Rebecca Kelly (of KX), Devon McCormick, Morten Kromberg, Simon Garland, and Stephen Taylor reflected on their experiences of working with and learning from Iverson. The legacy of Iverson Notation for APL, J, Q and other languages was discussed, together with the future of Iversonian notations.[5]

After a consensus at the September 9th 2021 webinar, BAA headed an effort to adopt a universal vendor-agnostic logo for APL. This work concluded at the 2022-05-19 webinar.

Organisation

The BAA is administered by a committee of officers elected by ballot of Association members at the Annual General Meeting. Working groups are also established in areas such as activity planning and journal production. Offers of assistance and involvement with any Association matters are always welcomed.

Funding for the BAA comes entirely from the sustaining members. In many cases, these sustaining members also provide manpower and administrative assistance to the association at their own cost.

The current chairman is Paul Grosvenor.
