<LANguage> A programming LANguage from Bell Labs. ALEF boasts few new ideas but is instead a careful synthesis of ideas from other LANguages. The result is a practical general purpose programming LANguage which was once displacing C as their main implementation LANguage. Both shared variables and message passing are supported through LANguage constructs. A window system, user interface, operating system network code, news reader, mailer and variety of other tools in PLAN 9 are now implemented using ALEF. (1997-02-13)
