This field specifies the name of a file to receive any error reports.
 An error file is useful since the import function is performing bulk
 operations that can result in errors scrolling off the screen.

 Errors are written into the file as comments, followed by the line from
 the input file that caused the error.  This allows you to use the error
 file as an IMPORT input file, after correcting the errors.  Using this
 method, only those operations that resulted in an error will be re-tried.

 If not specified, all errors are sent to the screen.
