If your case is like ours, namely a very large application with lots of intricate rules and exceptions (it's a payroll for the laws of Panama), little spare time available to migrate, and relatively little economic payoff from migration, consider what we did. Our main goal was not to be character based and to base the application on a well thought out OOP framework (Codemine) for easier future evolution.

As a witness, I should say that Alex achievement is just great. They did an excellent job with Erick and Edwin. The application (PayDay) is not a converted DOS app, but a truly, fully OOP application. CodeMine helped a lot, but the real merit is actually for them.

See you,
