Used by the routine at 61696 to hold the character number of whoever is being grassed up by EINSTEIN for writing on the board (206=BOY WANDER, or 210=ERIC); it is a submessage of message 88. Note that storing the character number (206 or 210) here is a mistake; it should be the message number of the character's name (27 or 31) instead. In any case, this message (along with parent message 88) is never used, because of a bug in the section of code at 61852.
