Thanks for the feedback.

I've used newobject() in other projects but this particular one is inherited code that, as I've mentioned before, uses set classlib.

The thing that I'm still unsure of is, does using newobject() reduce system resources (or offer other advantages other than not having to set classlib) when compared to set classlib? If it does, then I'd attempt to switch over to using newobject() instead. If not, then I wouldn't bother.

When I need to use a class in a classlib, I only type "NO myclass" and press F5 which I have programmed to invoke the dynamic snippet. I then get a picklist of every class in my project where myclass is found, and end up with the working code.

The same goes for procedures; SET PROCEDURE TO ... ADDITIVE. Is there any drawback to doing it this way? I was wondering if there is any advantages of loading them on a "as needed" basis. Something along the lines of
