I.P. Sharp Associates held a series of conferences in Toronto for APL programmers beginning in 1978. These user meetings were motivated in part by the lack of official 1977 and 1978 APL conferences, and the first was the only major APL conference held that year, while others were held in addition to APL conferences and possibly STSC conferences in the same year.[1] Proceedings were published by IPSA for all conferences, with the name "APL Users Meeting".
