Upper Case Translate turned off accidentally
Upper Case Translate is getting turned off unintentionally. We execute OLFU filename, enter CLR and then clear the screen and exit OLFU. The terminal then shows NOUCTRAN.
From the OLPS transaction, select Option 0 (OLFU Maintenance) then Option 8 (T/S Retention). Change this setting from 'C' to 'R'. This should prevent the case translate from changing without using the LCA or UCA functions.
