Copying data to the import file in a fixed format (CPYTOIMPF command)
When you copy data to the import file in a fixed format (DATFMT(*FIXED)), each field of the file is copied. A null indicator on the command NULLS(*YES) places either a 'Y' or 'N' following the field data in the to-file indicating if the field is null or not.
