> but Algol really does seem dead Unisys still actively maintains their MCP mainframe operating system, which is written in an Algol superset (ESPOL/NEWP), and comes with a maintained Algol compiler - https://public.support.unisys.com/aseries/docs/ClearPath-MCP-21.0/86000098-519/86000098-519.pdf https://public.support.unisys.com/aseries/docs/ClearPath-MCP... - and they continue to add new features to Algol (even if minor) So, no, Algol isn’t dead. Getting close but still not quite there. There are better candidates for dead languages than Algol, e.g. HAL/S (programming language used for the Space Shuttle flight software)
