I don't think this is possible with a macro. It would have to be written
into the macro interpreter itself because it would have to keep the
knowledge of what &VAR was while looking at what was defined to %IN(). Any
macro you would write would not be aware of what just preceded it in the
macro code. How could it possibly pick this up?

You could always do it like this:

%IF %INDEX(%quotelst(A B C),"&VAR") %THEN...

...so long as you use the %quotelst macro here.

If this is not the case then I would be happy to be proved wrong.
