Command for having a list of variables of an equation?

I know that reserved variables A...Z are special. This is the reason why i put in the formula V=R×I0 where I0 is a capitol 'i' with a zero '0'. The 'I0' is not a reserved variable (A...Z).

With the command: lname ( V = R × I0 )
I was expecting [ V R I0] or [ I0] for the reason above regarding reserved variables.

The issue is that i only receive [ ] as answer.

Is that normal?

That is an issue discussed otherwhere on this forum, in CAS you must add quotes to the formula ie lname('R=V*I0'), that provides [R V I0], lname(Quote(R=V*I0)) again yields an empty list. So it seems to be difficult to be used in a program.
