Issue/Introduction

After upgrading to Endevor 18.0.12 some of the panels in Endevor and Quickedt are not working properly.  Under a selection list, if I enter 'left' or 'right', I get a command error.
The function keys work fine.   Why is this happening and how can I fix it? 

Environment

Release:
Component: ENDBAS

Resolution

The upper case 'LEFT' and 'RIGHT' work as expected, as well as the function keys.  Corrected by PTF SO08044:
