Your Inventu Viewer+ service has a default pad character already defined. In some applications, one screen may use underscores while another uses dashes, or blanks. On a screen-by-screen basis you can control the pad character to use with this field.
Since the null (ASCII zero (0)) cannot be keyed the way a dash or underscore character can, the special entry of \0 (backslash with a zero character) will be interpreted as the null at runtime when the definitions file is processed.
Note that this value will be ignored if the connection has PaddingMode=no or this screen has PaddingMode=no.
