Return control to program on using TAB or arrow keys from display.
jeevan....@gmail.com
I have come across a requirement, where I have to return the control
to RPG program from a display file, upon exsiting from a I/O capable
field either by TAB key or by arrow keys. So the data can be processed
in the RPG program.
Thank you.

keys give control to the program.

The nearest thing i know is that you can define a display attribute to
a field (can't remeber the exact one, look it up), which will result
in control returned when field exit is pressed or the cursor is at the
end of the field when typing.
There are no method however to control leaving the field by arrow keys
or tab.

ER
End of record; equivalent to AUTO(RA)
Use this code so that the workstation user does not need to press the Enter
key. Whenever the workstation user keys a character (including a blank) into
the last position of the field, the record is sent from the device just the
same as if the Enter key had been pressed. If you also specify DSPATR(SP)
for the field, the record is sent from the device as soon as the workstation
user selects the field. If you use this function, it should be on the last
field typed in by the user for this record.
Option indicators are valid for this keyword.

Thank you for the response. I have checked with the CHECK(ER) keyword.
This keyword works with 'field exit' key, and simulates the 'ENTER'
key. But I have to pass the control to the program once the user
leaves a field, either by TAB or by the arrow key. So I have no idea
how to pass the control back to RPG, when the user leaves a field by
these two keys. I guess the DSPATR(SP) is to work with the field
selection by light pen, and that too upon selection of a field. It
seems quite different from my requirement.
Any suggestion most welcome.
Thank you.

I have 2 suggestions for you which are most likely not what you want:
1) Use the waitrcd(X) keyword when generating the dspf. Then write the
record & read the file. This will return control to the program &
seton the %error flag when X seconds have passed if the user hasnt
pressed a function key or enter etc. Then you can check the cursor
position. This results in a lumpy response to the users.
2) Have the field they want to change 'pop up' in a window. The user
can only chnage the 1 field then you can validate it when they press
enter & move onto the next. You can move a single window reound the
screen if you need to do this on a few fields & want to make it look
like the field is 'highlighted'
