Encode a long X.400 DD.RFC-822 attribute into continuation attributes.
ENCODE DDRFC822 dd.rfc-822-attribute-value-pair
Command Qualifiers Defaults None. None.
dd.rfc-822-attribute-value-pairA DD.RFC-822 attribute value pair.
X.400 Domain Defined Attribute values are limited to a maximum of 128 characters. Internet addresses are normally "embedded" into an X.400 address by representing the Internet address using the X.400 DD.RFC-822 attribute; but since Internet addresses may be longer than the X.400 DDA value limit, a single DD.RFC-822 attribute value may not be able to contain an entire long Internet address. To handle this case, three additional "continuation" DDA's have been defined, DD.RFC822C1, DD.RFC822C2, and DDRFC822C3. A single Internet address may be split among these four DDA's, thus allowing Internet addresses of up to 512 characters to be embedded into an X.400 address.
The ENCODE DDRFC822 command encode a "long" X.400 DD.RFC-822 attribute value---one with more than 128 characters into the value---into a DD.RFC-822 attribute plus continuation DD.RFC822Cn attributes.
