Re: Looking for Advice/Suggestions

[Kelley <kelley.work@xxxxxxxxxxx>]

This is purely an educational adventure for me. My approach to this 
exercise is that the business logic will stay on the IBM i.

In reality, the facility I work at will be shutting down in the next few 
months. We are the only facility that uses an IBM i. All of our code 
will be transferred to tape and placed in a fault.
