Introduction To Function Key AID Bytes
Function Key AID bytes can be used to determine which key was pressed in an interactive program. Using the Workstation Data Structure the function key pressed can be retrieved from 369 position. The AID byte will help you determine which actual key was pressed. Using the AID bytes also allows you to perform any things without using indicators. The File Information Data Structure can be found in the RPG IV Reference, File and Program Exceptions and Errors section. Look at Device Specific Feedback.

Examples of AID Byte Usage
For example, using a display file with the F3 key defined as an exit key, we can define the CF function like this:
A CF03
Inside the RPG program we can use the AID bytes to determine if the key pressed was in fact F3.
Dwsds ds
D fkey 369 369a
/free
DoU FKey=x'33';
// do more stuff
If FKey=x'33';
Leave;
EndIf;
EndDo;
/end-free
Even better would be to define F3 as a named constant:
Dwsds ds
D fkey 369 369a
D F3 c Const(x'33')
/free
DoU FKey=F3;
// do more stuff
If FKey=F3;
Leave;
EndIf;
EndDo;
/end-free
