From Werner Paulus Migrations System:
This reverse engineering software helps you as a programmer to check your software and get a better understanding of the interrelationship among all the pieces. You can find out the changes you made between 2 versions, members that should not be in a specify library, members that refer to other members that do not exist, or members that are not used by any other member. Standard language reports show you the bill of material of a member as well as the global usage of a part. In its current Version the product covers MVS JCL, Cobol, Copy, DBD, PSB, DB2, QMF, REXX and HTML all in a beta version. A new version covering the most important internet languages is on the way. New in this version is a online search facility, that find all occurrences of a word across all source types.
