James,

The objective in the object model is to provide an interface that the pgmr
programs to. The complexity below the interface is the concern of the
interface provider. In os400, the interface are cl cmds and system api's. To
illustrate my point re: the client server model adds complexity to a system,
consider how much more complex ( harder ) os400 would be to for the pgmr if
all the interfaces were via dtaq instead of pgm calls.

The only tradeoff I see that justifies the client/server model is the low
horsepower of a CFINT system. Get rid of CFINT, remove the need for
client/server, reduce complexity of as400 applications, improve the
viability of our system.
