It appears that the set command cannot override a variable specified as

For example:
MACRO (ADD_GADB RCMD)
does not accept changes to RCMD within the macro using the set command.
Is there a way to override this?

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
I would argue that the following snippet of code should either print
CAT twice or die. Unfortunately it first prints DOG and then CAT.
Thanks,

MACRO(FOO BAR)
SET (BAR CAT)
MESSAGE(${BAR})
ENDMACRO(FOO)
FOO(DOG)
MESSAGE(${BAR})

Ok,
But cpp doesn't discriminate between ${BAR} and BAR.
#include iostream
using namespace std;
#define foo(x) x = 3; cout x \n;
int main()
{
int y = 1;
foo(y);
cout y endl;
}

I said like cpp, not exactly cpp. The difference is you have to use ${} to
expand
