'''APL*PLUS''' (stylised as '''APL⋆PLUS''') was originally the [[APL\360]] derivative jointly marketed by [[STSC]] and [[IPSA]]. Eventually the companies parted ways, and IPSA re-branded their product as [[SHARP APL]].

APL*PLUS was an extension of APL\360, and as such was written in [[wikipedia:IBM_Basic_Assembly_Language_and_successors|IBM\360 assembler]]. STSC reimplemented the language in [[wikipedia:C (programming language)|C]] for the [[wikipedia:IBM PC|IBM PC]], and released it as APL*PLUS/PC in 1982. A derivative "2nd generation APL", adopting extensions from [[NARS]] and later [[APL2]] was released in 1989 as APL*PLUS/II.<ref>[[STSC]]. "APL*PLUS II User's Guide". 1989. Cited by [https://dl.acm.org/doi/10.1145/97811.97877 Design and implementation of the interface to compiled languages in APL*PLUS II] at [[APL90]].</ref> A further version was called APL*PLUS/III.

In 1992, STSC changed name to Manugistics, and in 1995, APL*PLUS was sold off to LEX2000 Financial Reporting Software, which then created a subsidiary named APL2000. The product was re-launched as APL+, with specific names APL+Win and APL+Unx for [[wikipedia:Microsoft Windows|Microsoft Windows]] and [[wikipedia:UNIX|UNIX]], respectively. When UNIX support was abandoned, [[APL+Win]] became the sole product.
