A few questions:
- Why are AVars and DelAVars not mentioned in the catalog menu?
- Once an AVar is created, such as AVars(“vtest”):=123.456, what’s the difference between vtest:=654.321 and AVars(“vtest”):=654.321 ?

They are. They appear under the app var function menu as they are app specific. If you press the CATLG button however, do you see how it has a > on the side and a multi app icon? You will see a copy of each app there to pick a specific one.

Nothing essentially. The first will be slightly faster however.
