44236: Handle A Class 160 Word
Used by the routines at StartPictureModeScreenIdle, CopyDisplayIfNeeded and RememberDisplayPage.
Skips class 160 tokens, saves the word pointer and this clause record, and carries on at the class 176 matcher (MatchWordAgainstEarlierClause). When the parser count at 40985+1 is 2 it sets bit 6 of the clause record first.
