PLEX is a special-purpose, concurrent, real-time programming language. The proprietary PLEX language is closely tied to the architecture of Ericsson's AXE telephone exchanges which it was designed to control. PLEX was developed by Göran Hemdahl at Ericsson in the 1970s, and it has been continuously evolving since then. PLEX was described in 2008 as "a cross between Fortran and a macro assembler."
