ObjectScript is a general purpose object-oriented programming language developed by InterSystems Corporation. It is designed to be simple to learn, easy to use, yet still powerful, combining the convenience of an interactive interpreter with many of the features of Java:

  • a simple java-like syntax
  • class system, with single inheritance and mixins
  • private/protected/public fields and methods
  • exceptions for error handling
  • synchronization and threading
  • compiles to bytecode for higher performance
  • osdoc: a javadoc-like tool to extract API documents
  • from src code, plus API docs accessible reflectively
  • XML-RPC support
  • Windows COM support
  • regular expressions (requires java v1.4 or later)
