Causes error messages from the Import batch transaction to be written to the file name specified after this command (called the error log file). The syntax is:
ERR_LOG_FILE = filename;
where filename is the name of the file, including extension and path, for the error log file.
If you don't specify a path, the error log file is put in your current directory. Error messages are still displayed on the screen. ERR_LOG_FILE is an optional batch Import command.
For example:
ERR_LOG_FILE = C:\LOGFILES\BATCH.ELF;
saves error messages to the batch.elf file.
