MAIL$_MESSAGE_BACK

   When you specify the Boolean item code MAIL$_MESSAGE_BACK,
   MAIL$MESSAGE_MODIFY reads the identification number of the
   specified message in order to return the first record in the
   preceding message.

   Specify the value 0 in the buffer length and buffer address
   fields of the item descriptor.

   Do not specify the item codes MAIL$_MESSAGE_BACK, MAIL$_MESSAGE_
   ID, and MAIL$_MESSAGE_NEXT in the same call to MAIL$MESSAGE_
   MODIFY.
 

MAIL$_MESSAGE_FLAGS

   MAIL$_MESSAGE_FLAGS specifies system flags for new mail. The
   buffer address field of the item descriptor points to a word that
   contains bit mask offsets. The following offsets can be used to
   modify the 2-byte bit mask:

   o  MAIL$V_replied

   o  MAIL$V_marked
 

MAIL$_MESSAGE_ID

   MAIL$_MESSAGE_ID specifies the message identification number of
   the message on which an operation is to be performed. The buffer
   address field of the item descriptor points to a longword that
   contains the message identification number.

   Do not specify the item codes MAIL$_MESSAGE_BACK, MAIL$_MESSAGE_
   ID, and MAIL$_MESSAGE_NEXT in the same call to MAIL$MESSAGE_
   MODIFY.
 

MAIL$_MESSAGE_NEXT

   When you specify the Boolean item code MAIL$_MESSAGE_NEXT,
   MAIL$MESSAGE_MODIFY reads the message identification number of
   a message and returns the first record in the message following
   the current message.

   Specify the value 0 in the buffer length and buffer address
   fields of the item descriptor.

   Do not specify the item codes MAIL$_MESSAGE_BACK, MAIL$_MESSAGE_
   ID, and MAIL$_MESSAGE_NEXT in the same call to MAIL$MESSAGE_
   MODIFY.
