RE: when user presses ENTER key in Display screen How to detect it in an RPG program?

There is an Hexadecimal value associated with the enter key. The hexadecimal 
value for the enter key is X'F1'. On your display file information data 
structure (INFDS), POSITION 369 to 369, you need to define an alpha field. That 
field will tell you which key has been pressed. You need to define as a 
constant the name of the enter key that you are going to use.

Example:

  * Display File                                  
 FTEST01    CF   E             Workstn InfdS(DSPDS)

 D #ENTER           C              CONST(X'F1')

* Display information data Structure
 D DSPDS        SDS  
 D  @FKEY                   369      369

   IN YOUR LOGIC, you will say;

           If @FKEY = #ENTER

Hi Shijith,
i'm not that pro then it comes to interactive programs, but in our 
displayfiles we define a valid command key.

VLDCMDKEY(26 'return') 
on filelevel.

I guess then you could do a 
if *in26=*on

This should be true if the user just hits enter.
If the user presses F1 to leave the display *in26 shouldn't be *on.

greets,
 Martin
