>I know that using WITH/ENDWITH yeilds a proformance gain because the system doesn't have to drill down to the object refrence in question but does WITH This have the same effect? It seems to me that it is the current object anyway so no drilling has to take place anyway.

The performance gain when only going one level deep is negligible or non-existent. The performance gain is only noticable when working with nested objects.

The reason I use With/Endwith for single level operations is readability. I think it's easier to understand and it saves me some typing. ;-)
