Only L or R are permitted for this field. 'L' indicates that the output is left justified i.e. Printing commences from the left hand side, 'R' indicates that it is right justified, i.e. Printing commences from the right.

The value entered here will become the default value for justification when entering the values in the prompt definition screen (option 5 of the main menu). However, it should be noted that the values on the file layout are not changed to the new value if the default is overridden in option 5.
