Sorry, I have just one more question.

Normally I clear variables before assigning values so no mistakes are made.
But the

Use Unset
Overbar[p]

only works when Overbar[p] has assigned a value otherwise you will get an
error/warning. Is there a way to avoid this, like asking if a variable is
already assigned a value.

TIA
Martin
