Panel C1SD1000 can be displayed in two ways;
1 - if  VNTUIELM=S the selection is in short mode
2 - if  VNTUIELM=L is in long mode.
The default is defined in ENDICNFG with option UI_OPT_ELEMENT.

After using option UI_OPT_ELEMENT=L, how can i change this default to short mode (S).
I have tried to modified ENDICNFG table specifying UI_OPT_ELEMENT=S but i still have long mode display.
The option UI_OPT_ELEMENT from ENDICNFG is read when user profile is not present (if there's a new user).
When ISPF profile is created the value is recorded from the value of UI_OPT_ELEMENT to record VNTUIELM.
Then if a profile already exists and option set is changed in ENDICNFG table later, the change has no effect.
The only solution is to clean up the user profile or force the value in the panel C1SO0000.
