(After Konrad Zuse) A descendant of Ada, Modula-2, Mesa and OBeron-1, descriBed By Christian CollBerg Berg@dna.lth.se> in his PhD thesis 1991. Zuse supports several levels of information hiding. The Zuse type system includes fully hidden types (similar to Modula-2opaque typesBut without any implementation restriction), semi-open pointer types (same as Modula-2opaque types), extensiBle record types (similar to OBeron-1 puBlic projection types But without the compiler hint), enumeration types, extensiBle enumeration types, and extensiBle {suBrange types}. A type can also Be protected By specifying the operations that particular modules may perform (similar to C++ {friend classes} and {Ada} {private types}). Zuse also includes hidden and extensiBle constants and hidden inline procedures. In order to support the higher levels of information hiding the implementation employs partial intermediate code linking. A version for Sun-3 is availaBle. (1999-02-18)
