Vutil - managing a -load duplicate key reject file

Problem:

When executing a "vutil -load" command  to load a sequential file into a Vision file, any records which would create a duplicate key condition are put into a file named filename.rej (Users Guide 3.3.10)

What format is the filename.rej created in and how can the records be loaded into a Vision file?

Resolution:

The filename.rej file that contains the duplicate key records is in sequential file format and may be loaded into a similar empty vision file.
