An export is performed on machine A. The export file is transferred (via FTP, for example) to machine B in character (ASCII) mode rather than (BIN) binary mode. An import of the file is done on machine B.

One of the following errors can result:

IMP-9 abnormal end of export file
// *Cause: This is usually caused by an export file generated by an aborted
// export session.
// *Action: If the export file was generated by an aborted export session,
// retry the export followed by the import. Else, report this
// as a bug and submit the export file that causes this error.

IMP-30 failed to create file %s for write
// *Cause: Import was unable to create the specified file with write enabled
// *Action: Check the file name and file system for the source of the error

IMP-37 Character set marker unknown
// *Cause: export file is corrupted.
// *Action: Try to obtain an uncorrupted version of the export file.
