ZUSE
ZUSE
(language)Zuse
(language)Zuse supports several levels of information hiding. The Zusetype system includes fully hidden types (similar to Modula-2opaque types but without any implementation restriction),semi-open pointer types (same as Modula-2 opaque types),extensible record types (similar to Oberon-1 publicprojection types but without the compiler hint), enumerationtypes, extensible enumeration types, and extensible subrange types.
A type can also be protected by specifying the operations thatparticular modules may perform (similar to C++ friend classes and Ada private types). Zuse also includeshidden and extensible constants and hidden inline procedures.In order to support the higher levels of information hidingthe implementation employs partial intermediate code linking.
A version for Sun-3 is available.
