MEMO - Memo character (internal class - not supported as interface)
MEMO values are considered as 0-terminated text fields, which may use any of the supported encoding types (ASCII, LATIN1, LOCAL, STRING, UTF8, UTF16, UTF32). MEMO values are used to store large text fields in the database. Since memo values are stored as references and not directly in the instance, they will occupy storage only in the size used for the text data.
