The unformatted REWRITE statement performs the following operations:

• It retrieves binary values from internal storage.

• It writes the untranslated data to a current (existing) record in the following types of files:

  • On OpenVMS systems, in a file with any type of organization. (In sequential files, the new record must be the same length as the current record.)

  • On Tru64 UNIX systems, in a file with direct access.

  The current record is the last record accessed by a preceding, successful indexed (VMS only), direct access, or sequential READ statement.

Errors occur under the following conditions:

• If you attempt to rewrite more than one record in a single REWRITE statement operation

• If a record is too long (Unused space in a rewritten, fixed-length record is filled with zeros.)

• If the primary key (VMS only) value is changed
