language (DIANA) A formerly de facto standard

intermediate language for Ada programs, developed by Goos

and Wulf at CMU in January 1981. DIANA is an attributedtree 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
