Hermes (programming language)
Appearance
Hermes is a language for distributed programming that was developed at IBM's Thomas J. Watson Research Center from 1986 through 1992. Hermes' most interesting features included [1]:
- 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, appear to have been the earliest programming languages supporting this form of initialization checking.
