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.

=== 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.<ref>Stephen Taylor. [http://archive.vector.org.uk/art10009870 "Editorial: Discover, Learn, Profit"]. Vector journal volume 21 issue 4. 2005-09.</ref> 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 [[wikipedia:COVID-19 pandemic|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|BAA Webinar}}
BAA began a series of [[Wikipedia:webcast|webcast]]s 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.


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.

The events are held at 16:00 UK time, every other Thursday on even-numbered [[wikipedia:ISO week|ISO week]]s. The current week number can easily be determined using Dyalog APL: <syntaxhighlight lang=apl inline>⍬2⊃¯11⎕DT'Z'</syntaxhighlight> gives <code>{{CURRENTWEEK}}</code> this week.

=== Webinar ===
=== Individual events ===
In response to the restrictions imposed during 2020 by the COVID-19 pandemic, BAA has arranged a series of [[Wikipedia:webcast|webcast]]s to replace their regular monthly symposium.<ref>BAA. [https://britishaplassociation.org/webinar-schedule-2020/ Webinar Schedule for 2020].</ref> The series proved popular, and was continued throughout 2021<ref>BAA. [https://britishaplassociation.org/webinar-schedule-2021/ Webinar Schedule for 2021].</ref> and into 2022.<ref>BAA. [https://britishaplassociation.org/webinar-schedule-2022/ Webinar Schedule for 2022].</ref> Initially, each event consisted of half an hour of social interaction, followed by a single presentation of about an hour, and a Q&A session, though some webinars were so-called ''open sessions'' which are more similar to the monthly symposium, in being informal meetings where APLers discuss and present whatever they feel like, with no particular subject decided on beforehand. Eventually, the series evolved so that most meetings were of this general meetup nature, with only a minority of events having an agenda. 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 [[wikipedia:ISO week|ISO week]]s. The current week number can easily be determined using Dyalog APL: <source lang=apl inline>⍬2⊃¯11⎕DT'Z'</source> gives <code>{{CURRENTWEEK}}</code> this week.

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 [[Family_tree_of_array_languages|other languages]] was discussed, together with the future of Iversonian notations.<ref>BAA Editor.
