Diagnosis
Screen element &V1& has defined length 0.
Value 0 for the defined length usually signalizes an error situation.
This value 0 can also arise if &V1& is a screen element with aDictionary reference where the attribute "Dict. modifiied" is not set,and the output length of the referenced Dictionary element is largerthan the maximum allowed defined length of 255. In this case, when thescreen is read, the system uses the value 0 instead of the value that istoo large and cannot be displayed.
The length values are of core importance for both display and editoptions in both layout editors.
The Graphic Layout Editor cannot handle screen elements with definedlength 0 and therefore deletes them. For this reason, the system has tofully reject any attempt to call up the Graphic Layout Editor andbranches instead to the Alphanumeric Layout Editor.
In the Alphanumeric Layout Editor, screen elements with defined length 0cannot be selected and can only be recognized through their shading.
Operations on screen elements with defined length 0 should not,therefore, be executed in the Layout Editor but in the element list. Inthe element list, you can enter an appropriate length. Also, theattributes "Dict. modified" and "Scrollable" can be set. In addition,deletion of the screen element is possible.
