SET KEY for ENTER

Hi,

I have a map (which basically has information to be read from, that it is a reference map) and this is a third level map. A PF3 on this takes to the previous map. ENTER key is also doing the same (since by default ENTER key should function like that).
Is there a way to disable this ENTER key on the map - that is, on depressing the ENTER KEY , no action should happen on the map.
Is there a way that has been tested and verified.

Regards,

SET KEY ENTR=OFF doesn’t work…

So the only way I now is to write the following PF-KEY-RULE into the MAP.

IF *PF-KEY = 'ENTR'
  REINPUT WITH TEXT 'ENTR is not allowed!'
END-IF
