Curly brackets do nothing to protect the contents of a variable. Using them
tricks new bash coders into thinking they are protected when they are not.
To avoid propagating the damaging myth, only use them when you actually need
them (eg to protect the variable name from following characters, not its
contents).

That's just going to be the contents of a msx= command line option defined in
the
script header's #% definition.
