This is a good example of having demands from your customers/users that 
exceed what is possible with the 5250 datastream!

In 5250, the system sends an entire screen of data to the emulator. Then, 
it's the emulator's job to deal with everything that the user types until 
he/she hits ENTER or a function key (what they call an AID generating key)

When the user hits Field+ or FieldExit or Field- or anything like that, 
the emulation software adjusts the field as appropriate and moves the 
cursor to the next field.  Nothing gets sent to the iSeries. The iSeries 
doesn't even know that there is a FieldExit key.  For all it knows, the 
user typed the field right-adjusted in the first place.

There's a special code that the iSeries can send to the emulator when it 
sends the screen that says "if the user exits this field, pretend he/she 
pressed ENTER"... in other words, CHECK(ER)  but, the iSeries doesn't know 
anything else about it, aside from "the auto-enter was triggered"

The 5250 protocol is designed for 1970's green screen terminals. Since you 
clearly have the need, you should consider upgrading to a Web interface or 
a true GUI interface.
