Sorry for entering late to this conversation. I may have missed some key piece of information earlier in the thread, but let me ask a "dumb" question, anyway. plexit ultimately calls exit, which AFAIK immediately exits without returning control to the routine that called the plplot library in the first place. So plexit should be reserved (and I think it normally is) for truly catastrophic errors where no means exist to recover. For that case where a castrophe is occurring anyway, why are we concerned about memory management issues? Why does plexit even bother to call plend? Shouldn't it just send a message about the castrophic error and exit? Alan __________________________ Alan W.
