Re: Green-screen versus browser

I think I've seen a mix years ago.  It was a real estate package that 
would pull up a picture of the house.  Or an employee package that would 
pull up a picture of the employee.  Basically, a canned package to enhance 
your existing applications by adding this capability.

Personally, I'd rather see the entire application be GUI or the entire 
application be green screen. I don't like it when someone mixes the two 
like this. (Just my opinion, of course.)

Shrug...  The spawn() API could be used so that you have multiple jobs 
instead of multiple threads. You could have one job that reads the socket 
and write's the data to a data queue.  Another that reads a data queue and 

puts the results onto the socket.  Then the interactive job could work 
purely with data queues, which can be attached to the display file to 
allow multiplexing.

Like I said, I don't like this type of coding. I'd rather see all 5250 or 
all GUI. And that's my recommendations to programmers who are trying to 
implement this. But if you MUST mix them for some reason, it's not 
impossible.
