        1.  {A. K. Erlang}.  (The other senses were named
        after him).
     
        2.  A concurrent {functional language} for large
        industrial {real-time} systems by Armstrong, Williams and
        Virding of Ellemtel, Sweden.
     
        Erlang is untyped.  It has {pattern matching} syntax,
        {recursion equations}, explicit {concurrency}, {asynchronous
        message passing} and is relatively free from {side-effects}.
        It supports transparent cross-{platform} distribution.  It has
        primitives for detecting run-time errors, real-time {garbage
        collection}, {modules}, {dynamic code replacement} (change
        code in a continuously running real-time system) and a
        {foreign language interface}.
     
        An unsupported free version is available (subject to a
        non-commercial licence).  Commercial versions with support are
        available from {Erlang Systems AB}.  An {interpreter} in
        {SICStus Prolog} and compilers in {C} and Erlang are available
        for several {Unix} {platforms}.
     
        {Open Telecom Platform} (OTP) is a set of {libraries} and
        tools.

        3.  36 {CCS} per hour, or 1 call-second per second.
     
        Erlang is a unit without dimension, accepted internationally
        for measuring the traffic intensity.  This unit is defined as
        the aggregate of continuous occupation of a channel for one
        hour (3600 seconds).  An intensity of one Erlang means the
        channel is continuously occupied.
