Hello, Charles:


As others have pointed out, one way you can do something similar is to
create a (never-ending) "server job" to service requests.

Traditionally, (going back to System/38 CPF), you would implement this
approach using data queues. Today, you might also want to consider using
a TCP/IP sockets interface. One advantage of the TCP/IP sockets
approach is that the client programs can run on a PC under Windows or
Linux, or on another Unix or Linux server, or even another iSeries
system, while the "server jobs" run on your System i.

I like the sockets approach. If display logic is separated
from business rules (an MVC pattern) , then your UI
wouldn't even have to be on the AS/400; it could be
implemented in the language du jour.
