Trim whitespace on Input? - When selecting this, any leading or trailing whitespace is removed automatically from the input data for all elements. The non-leading or trailing whitespace is not affected.
Pad to minimum length on output? - When selecting this the output is padded to the minimum size with either spaces (character) or zeros (binary).
Import File/Version/Date - These are read only and used only to record when the import was made and in some cases the version of the source that was imported.
