(COND ((AND (EQ LINE WINDOW-LINE)
(> (PLINE-TICK WINDOW PLINE) LINE-TICK)
this ">" is never true, as far as I can see. I'm not sure what this is supposed
to do, probably a comment would be worthwhile here.
OK, I guess I see. Evidently redisplay causes a redundant tick, so
this ">" really means "=".
I must say, I don't know what you're talking about. If you read the
thesis you should know what this code is for. If it were never true,
ZWEI would always redisplay all lines. If I changed it to "=", it would
never be true, and ZWEI really WOULD redisplay all lines. If you look
at ZWEI you will see that it does in fact work. I assume that no two
values of the clock will be equal, since every interesting event
causes the clock to tick.
