This Natural profile parameter is used to specify the default filler character to be used for fields displayed by an INPUT statement.

Possible settings	any character	Default filler character.
Default setting	X'00'	For TTY, web I/O (with the Natural Web I/O Interface) or batch mode, the default setting is X'40', i.e. blank in hexadecimal format.

Notes:

1. The default filler character is used to pre-fill non-protected input fields (field attribute specification AD=A) when fields are written to a terminal by an INPUT statement.
2. For modifiable input fields (field attribute specification AD=M), it is used to fill the rest of the field.
