You are quite right in the following sense.
Local macros (N.B. _not_ local variables) are just named things with
string content. They do not possess formats. The question "What is the
format of this local macro?" has the answer: it doesn't have one.
Macros just are.
But you can use a -format- to convert one string into another. That is
shown by Maarten's example.

Thank you for your email. I always thought, I think I read it on this
list that local variables are strings and can't be formatted. Thank
you for your time.
