Option 30 (Padding Data) You can add characters to one side of a field to "pad" the field.
Padding allows you to fill in the remaining spaces when the
entered data does not fill an entire field.
If a variable length field is not completely filled with batch data,
this option fills the remaining positions in the field with the
character designated by Option 30.

Sample Use for Padding
If you have a variable length bar code that you want to occupy a
fixed amount of space on the supply, use pad characters. If the
maximum number of characters in the bar code is 15, but the
batch record only has 10 characters, the padding option fills the
remainder of the field with pad characters.
