VARRAW is made up of a 2-byte binary length subfield followed by a
RAW string value subfield.
VARRAW results in a
VARRAW with a 2-byte length subfield and a maximum size of 4 KB (that is, the default).
VARRAW(65000) results in a
VARRAW with a length subfield of 2 bytes and a maximum size of 65000 bytes.
VARRAW fields can be loaded between systems with different byte orders if the appropriate technique is used to indicate the byte order of the length subfield. See "Byte Ordering".
