Abstract:Object wrappers have been presented as a way to allow legacy applications and object-oriented applications to work together. However, object wrappers do not always solve the interoperability problem for COBOL legacy applications. The use of object wrappers is examined and 2 other types of wrappers, the procedural wrapper and the combination wrapper, are introduced for practical use with COBOL legacy applications. The main concerns of a developer of an object-oriented application that uses the services of or provides services to a legacy application are addressed. Examples of "real-world" COBOL legacy applications are cited and samples of all 3 types of wrapper code are provided.
