Hermes (programming language)
Hermes[1] [2] is a language for distributed programming[3] that was developed at IBM's Thomas J. Watson Research Center from 1986 through 1992. Hermes' primary features included:[4]
- 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.[5] Typestate was actually used more extensively, to generate compiler-inserted "delete" operations.
