APL*Plus and Sharp APL are versions of APL\360 with added business-oriented extensions such as data formatting and facilities to store APL arrays in external files. They were jointly developed by two companies, employing various members of the original IBM APL\360 development team.<ref>{{cite web |url=http://rogerdmoore.ca/INF/ERInstallationHistory.htm |title=History of I.

The two companies were [[I. P. Sharp Associates]] (IPSA), an APL\360 services company formed in 1964 by Ian Sharp, Roger Moore and others, and [[Scientific Time Sharing Corporation|STSC]], a time-sharing and consulting service company formed in 1969 by Lawrence Breed and others. Together the two developed APL*Plus and thereafter continued to work together but develop APL separately as APL*Plus and Sharp APL. STSC ported APL*Plus to many platforms with versions being made for the VAX 11,<ref>{{cite magazine |last1=Blumenthal |first1=Marcia |date=May 18, 1981 |title=VAX-11s Acquire APL Processor|url=https://books.google.com/books?id=MCFtKT_NaYIC&q=vax%20apl&pg=PA2|magazine=[[Computerworld]]|access-date= April 22, 2018}}</ref> PC and UNIX, whereas IPSA took a different approach to the arrival of the [[personal computer]] and made Sharp APL available on this platform using additional [[PC-based IBM-compatible mainframes|PC-XT/360]] hardware. In 1993, [[Soliton Incorporated]] was formed to support Sharp APL and it developed Sharp APL into SAX (Sharp APL for Unix). {{as of|2018}}, APL*Plus continues as APL2000 APL+Win.

In 1985, Ian Sharp, and Dan Dyer of STSC, jointly received the [[Iverson Award|Kenneth E. Iverson Award for Outstanding Contribution to APL]].<ref name="IversonAwards"/>
