  1. Megaprogram M e g a m o d u l e S e r v e r C H A I M S - C o m p i l e r CHAIMS ARCHITECTURE W r a p p e r D i s t r i b u t i o n L a y e r ( CORBA, DCE, DCOM, RMI …)

  2. CHAIMS LANGUAGE Designed for composition. Simple control operations. Untyped. Has following six primitives: SETUP ESTIMATE TERMINATE INVOKE EXTRACT EXAMINE

  3. CHAIMS-NEW IDEAS Language designed for software composition and reuse. Asynchronous task execution and runtime performance analysis. Simple language decomposes the traditional call statement. Communication between distributed heterogeneous sources. Generation of invocation codes for multiple interoperation protocols.

  4. CHAIMS-PROGRESS UPDATE Initial language and architecture defined. Two application models ready for testing. Online conceptual demo available. Paper presented at the fifth SAST97. (IEEE Computer Society, 1997, pages 44-51) CHAIMS megaprogramming language BNF, lexical analyzer and parser ready.

  5. CHAIMS-NEXT STEPS Completing the initial CHAIMS compiler. Development of CHAIMS runtime for CORBA. Service megamodule being developed to provide easy input and output. ( Remainder of FY 1997 )

  6. CHAIMS-LONG TERM PLANS Runtime for DCE and Active-X. Execute under multiple protocols and platforms. Optimization of invocation. Optimization of distributed data flow.
