st: Levelsof for more than one Variable

Subject   st: Levelsof for more than one Variable

I have two variables both containing string values. I would like to get all unique values (not the number of unique values) from these two variables jointly.

For example if I enter

levelsof var1, locals(loc1)
levelsof var2, locals(loc2)

I obtain all unique values of var1 and all unique values of var2. But at the end I would like to have one local containing only unique values in loc1 AND loc2.

Is there anyone who can help me with this?
