What I was trying to do was to avoid having to create a local variable.
The macro parameter is the default, which can be overridden if necessary.
Now I immediately have to set a new variable with the value of the
parameter. So I now have to account for another variable being created
which may then escape the macro's namespace.
Can we have the SET command fail on trying to set a macro parameter?
You are thinking about macros in the wrong way. Think of them as c or
c++ #define macro's.
Basically, they do nothing more than string replacement.
