>This would imply that NEWOBJECT() is slower...

As I said in the old thread I pointed to Naomi, I think it depends. Imagine you never ever use SET CLASSLIB OR PROCEDURE, then NewObject will waste time by removing the one it opened alone, which is presumably fast. On the other hand, if you only use SET CLASSLIB OR PROCEDURE, your safest (only?) option is to always use ADDITIVE, creating a big list of procedures, and then each time you use addObject fox will need to scan all those libraries to find the class in question. I am not saying that your implication is wrong, I just think it probably depends and is not really black and white to me.
