We show how hypertext-based program understanding tools can achieve new levels of abstraction by using inferred type information for cases where the subject software system is written in a weakly typed language. We propose TYPEEX-PLORER, a tool for browsing COBOL legacy systems based on these types. The paper addresses (1) how types, an invented abstraction, can be presented meaningfully to software reengineers; (2) the implementation techniques used to construct TYPEEXPLORER; and (3) the use of TYPE-EXPLORER for understanding legacy systems, at the level of individual statements as well as at the level of the software architecture - which is illustrated by using TYPEEX-PLORER to browse an industrial COBOL system of 100,000 lines of code.
