# APL conference

While many conferences and sequences of conferences have been held by the array language community, the term **APL conference** refers to a sequence of conferences held once per year, with some lapses, beginning in 1969, and ending in 2010 with no plans for future conferences. Initial conferences were organised by various universities or other institutions, with some connection to SHARE but no particular central authority. Beginning with the 1974 conference, APL 6, SIGAPL (or STAPL at the time) took over organization of the conferences. Conferences in 1977 and 1978 were not held primarily because of logistical failures, an occurrence which may have prompted vendors to begin holding their own IPSA and STSC conferences, but resumed afterwards and continued to be held every year until 2004. When no conference was arranged for 2005, Dyalog Ltd. began hosting its yearly Dyalog user meetings beginning in 2006, with both events happening in 2007. The last conference was held in 2010: organized in association with APL Germany and integrated with Dyalog's user meeting that year, it was seen as part of a sequence with the 2000 conference also in Berlin, but this sequence was not extended to 2020.

## Past conferences

### 1960s

#### 1969

The first APL conference was held at SUNY Binghamton, the first university with an APL system and sponsor of the conference, July 11–12 of 1969. It was called "The March on Armonk" after IBM's headquarters in Armonk: although attendees did not travel to Armonk, many came to make demands of IBM as they might at a march. Its stated goals were

(1) to bring together as a community of users those, primarily in university environments, who were using the APL\360 Terminal System;

(2) to indicate to IBM, both by what would transpire and by the volume of response, that the acceptance of the APL language had grown in a short period of time to an unusually high degree.^{[1]}

The high attendance of roughly 220 was due in part to IBM sales people: as IBM had recently begun to sell APL\360 as a stand-alone product, those in sales sought to learn about the language.^{[2]}

Attendee Garth Foster was motivated by the diverse interests represented at SUNY to rename his newsletter *SHARE*APL\360* to the *APL Quote-Quad*, and to establish the APL Implementer's Workshop. The latter served to bring the behavior of various APL implementations into closer alignment by offering implementors a forum to discuss design and implementation decisions.^{[3]}

A point of focus in early APL conferences was *CAI*, which stands for Computer Assisted Instruction. Sometimes the acronym CAL, or Computer Assisted Learning, is also used.

### 1970s

#### 1970

At the suggestion of NASA employee Cyrus Creveling, a group of attendees of the 1969 conference agreed to hold a second conference at the Goddard Space Flight Center in Greenbelt, Maryland. It took place on June 19 and 20, 1970. The conference, reduced in attendance from 220 to 150, was held in the style of a workshop, with presentations and discussion but no papers or proceedings published. At this conference the first formal effort to establish SIGAPL was made by collecting the required 25 signatures for a petition to the ACM.^{[2]}

Two reports from the conference were published in the APL Quote-Quad.^{[4]}^{[5]} Ken Iverson and Adin Falkoff attended but spoke little about their plans, and Eric Iverson, then at I.P. Sharp, participated in discussion.

#### 1971

The next APL conference was held at University of California on April 20 and 21, 1971. Again there were no formal proceedings, but summaries of each talk were printed in the next issue of the APL Quote-Quad.^{[6]} Following the failure of the petition to form SIGAPL produced at the previous conference, some attendees suggested forming an organization independed of the ACM, but Alan Perlis, a former ACM president, argued instead to continue working with the ACM.^{[2]}

The 1972 APL User's Meeting was held in Atlanta, Georgia on June 15 and 16. It was co-hosted by the Atlanta Public Schools Computer Center and Georgia Tech,^{[7]} and after the first day of presentations many participants toured the Computer Center, where APL was used including by students. Ken Iverson spoke at the closing luncheon the next day, discussing APL's development history and hinting at future directions. Submitted papers were refereed by Garth Foster.^{[8]}

#### 1979

The 1979 APL conference was held in Rochester, New York from May 30 to June 1, and sponsored by SIGAPL (then STAPL). In part due to the lack of formal 1977 and 1978 conferences, attendance was very high, with over a thousand attendees^{[3]} and 200 submitted papers. Abstracts could be submitted electronically by the major APL time-sharing services. Eight invited papers, presented to all participants, were given by notable computer scientists both inside and outside the APL community. In addition to talks, the conference featured a poster display and exhibits of APL implementations, terminals, and books. A banquet talk was given by Fred Brooks, with the title `⍉ 1 3 ⍴ 'APL' ⍝ A Sideways View of APL`
