Copying data to the import file in a fixed format (CPYTOIMPF
command)
148 File Management V4R5
When you copy data to the import file in a fixed format (DTAFMT(*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.
