===FlexOS, Concurrent DOS XM and Concurrent DOS 386 ===

[[Concurrent PC&nbsp;DOS]] later evolved into the modular [[FlexOS]] (1986). This exploited the greater memory addressing capability of the new [[CPU]] to provide a more flexible multi-tasking environment. There was a small but powerful set of system [[Application programming interface|API]]s, each with a synchronous and an asynchronous variant. [[Named pipe|Pipe]]s were supported, and all named resources could be aliased by setting [[environment variable]]s. This system was to enjoy enduring favour in point-of-sale systems.{{Citation needed|date=August 2024}}

Other successors of Concurrent DOS were [[Concurrent DOS XM]] (1986<!-- 1985? -->) and the 32-bit [[Concurrent DOS 386]] (1987).
