Hermes is a language for distributed programming that was developed at IBM's Thomas J. Watson Research Center from 1986 through 1992, with an open-source compiler and run-time system. Hermes' primary features included:

  • Language support of processes and interprocess communication.
  • Compile-time verification that operations use initialized data.
  • Representation-independent data aggregates called tables.
  • Lack of pointers.

    • The compile-time checking of data initialization, called "typestate analysis", is an early precedent for the definite assignment analysis performed by Java, Cyclone and C#.

    Hermes and its predecessor, NIL (Network Implementation Language), were the earliest programming languages supporting this form of initialization checking. Typestate was actually used more extensively, to generate compiler-inserted "delete" operations.
