Hi Bob,

I think what would solve the problem is checking for the hex code for the field exit key. I cannot find the hex value of the key in any of the books I have. They all only show X'3F' for Auto Enter and X'F1' for Enter. Is there a value for the field exit(+) key?

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.
