Keycode to string

With most objects, you can trap the key strokes using user events.
For example, on a datawindow object,
you can create a user event using Event Id = pbm_dwnkey.
In this event, you'll find a parameter of type keycode.
This is a predefined enumerated data type with values such as KeyA!, KeyB!, etc.
But if you want to convert this value to a string,
you'll find your choices are limited.
It looks something like this :

choose case a_key
       case keyA!
            ls_string = "A"
       case keyB!
            ls_string = "B"
       case keyC!
           ls_string = "C"
end choose

As simple as that!
