This filter expands an EBCDIC unsigned (as opposed to signed) packed decimal field to a raw EBCDIC number with no sign. Typically this filter is then followed by a Convert EBCDIC to ASCII filter - after all other fields have been expanded as well.

If your document contains COMP fields or packed decimals, use the mainframe copybook wizard, using the Treat 'COMP' as unsigned check box.

There are several notes to keep in mind when using this filter:

You MUST use this filter inside a Restrict to Byte Range filter. The field WIDTH is then set by the containing filter.
Expanding a field will increase your output record length, so ensure you allow for this. A good strategy to avoid problems is to first expand the rightmost field, then work your work back to the leftmost field. This prevents the field column positions from changing and makes the file easier to work with.
