2. +44 7941 452860 © Copyright 2006 Domino Software Ltd. Basic Conversion Issues  MANTIS is a robust and forgiving language –Define files, maps & routines that do not exist –Define datanames in the in-line code These are illegal in COBOL!

3. +44 7941 452860 © Copyright 2006 Domino Software Ltd. Conversion - Analysis  Check for Redundant Code  Re-iterative Process  Run until no redundant code remains  Redundant code retained as comments

4. +44 7941 452860 © Copyright 2006 Domino Software Ltd. Conversion - Analysis  Completeness check  Do all referenced components exist?  Files, Screens, Programs etc.  Passed back to user for resolution

6. +44 7941 452860 © Copyright 2006 Domino Software Ltd. Conversion - Analysis  Component Name Resolution  MANTIS allows much longer names  MANTIS names can user Cobol reserved words? These must be resolved  Conversion has defined defaults, but user has option to override

8. +44 7941 452860 © Copyright 2006 Domino Software Ltd. Conversion - Analysis  Check for code validity?  MANTIS allows programs to address data areas that are outside bounds?  Array of 10 MANTIS let’s you reference 11, COBOL doesn’t!  Field of 6 bytes, MANTIS let’s you reference byte 7, COBOL doesn’t! Must be resolved!

9. +44 7941 452860 © Copyright 2006 Domino Software Ltd. Now the CONVERSION!  Only when all the analysis issues have been resolved are we ready to commence the actual conversion!
