B16: Mixed_Record_Identifier; B17: Operation - Sony KV-DZ29M30 Service Manual

B16: MIXED_RECORD_IDENTIFIER
This keyword identifies a character string that can match characters at a specified
offset in a record. If the string matches characters in the record at the specified offset,
then that selects the FIELD(s) immediately below the MIXED_RECORD_IDENTIFIER.
Those FIELD(s) will be used to apply encryption or decryption to the record.
MIXED_RECORD_IDENTIFIERs are only used in files that contain records with
different layouts, such as where a header record, detail records and a trailer record are
written to a file.
Syntax:
MIXED_RECORD_IDENTIFIER <text> OFFSET <number>
Where:
OFFSET is a sub-keyword and <number> is the zero-based offset in the record where the
text to identify the record exists.
Example:
MIXED_RECORD_IDENTIFIER abc

If access is NOT granted, then the program will be able to read encrypted data, and
will receive an error if it tries to write data.
