Descriptive Intermediate Attributed Notation for Ada

(DIANA) A formerly de facto standard intermediate language for Ada programs, developed by Goos and Wulf at CMU in January 1981. DIANA is an attributed tree representation, with an abstract interface defined in Interface Description Language (Nestor, Lamb and Wulf, CMU, 1981; Snodgrass(?), 1989(?)). DIANA resulted from a merger of AIDA and TCOL.Ada. At the present (2001) it is no longer used by the major ADA compilers
