EnglishThis note examines the MODULA-2 approach to build data abstractions and abstract data types. MODULA-2 provides a byreference semantics by providing opaque types via pointers. The paper compares this mechanism with the one furnished by ADA (*). A comparison with object-oriented systems brings out the issue of assignment, copy and compare operations. That leads to a constructive methodology for abstract data types in MODULA-2. Any abstraction must furnish copy operations with two different semantics, respectively shallow and deep, and related equality and inequality operations. © 1988, ACM. All rights reserved.
