RE: Separating I/O from business logic

No duplication.  Once the rules are in a separate module, you use that
module in the server program.  I have only one program that holds the
business logic.  I have defined a way to transition from one large program
that does all to separate callable programs, to separate ILE modules if that
is the direction they want to go.  Finally to Client/Server.  Read again

Chris,
     Your method requires that the business rules be duplicated. Thus
maintained twice in the future. Don't make your life more difficult than it
already is.

     Use the existing display file enabled program. Just simply change the
workstation file to USROPN. Put an indicator on the new OPEN and CLOSE
statements and use the indicator to control the client/server modal.

     Instead of using DataQs directly, pass the I/O in *entry plist
parameters. Then write a driver program, using DataQs or Sockets, to call
the original application program and send/receive the data.
