Sounds at syntax time.... :) I certainly hadn't thought about that, and it seems unlikely that my first-quarter students will be clamoring for it, either. Nevertheless, it's true that a process-global hash table for external resources is more or less what I was thinking about. The question is (for the moment) moot, though, because it looks like the tool interface does everything I need. John
