Functions can be triggered by entering single-character statement codes in the statement code column.
In the default setting, when records are displayed in the data window, the statement code column can be overwritten while the data window is protected against overwriting. The data window lines are set to overwritable only when statement codes are entered in the statement code column or when data is transferred with [F2]. It is not then possible to specify any statement codes in the overwritable screen lines.
As an alternative to the default setting, the statement @PAR EDIT-FULL=ON can be used while the line number display is active (@PAR INDEX=ON) to set the data window and the statement code column to overwritable. It is then possible to enter a statement code and at the same time modify data in this screen line (see @PAR EDIT-FULL).
Invalid entries in the statement code column can be deleted by overwriting them with blanks or NULL characters.
