Tim,

Before you get too deep in theory, think about whether your program
containing your business logic can be used in a batch process.  If it
can, then you've already achieved step one of re-engineering, and now
you can start thinking about procedures, modules, service programs and
the like.  If not, then think about how you would strip your business
logic out of your 5250 programs.

Start small and build from there.
