Hello:

What exactly is the difference between using   u = 2cm   and   u := 2cm ?
If I have multiple figures in a file, and I re-define u with u=someValue in
subsequent figures, MP often complains about the value being re-defined.  If
I use := there's no trouble.  When is it correct to use = and when := ?

By the way, is it o.k. to post MP questions here or should I be looking
somewhere else?

Thanks and Best Wishes,

Matthew
