>1. It's really Thisform (not Thisform.DataEnvironment), because DE doesn't have SetAll method.

Ah, right. DE isn't a container. I didn't realize SetAll would drill down.

>2. To get database name you just use cDbcname=dbc(), assuming that database is opened already (I do it in Main.Prg).

I prefer to avoid this, since the database name is already present in the cursor(s).
