%macro abc(x);
%unquote(
%nrstr(%macro) &x(&x=1);
%nrstr(%put value of x is )&x which is %nrstr(&)&x;
%nrstr(%mend) &x;
)
%mend abc;

%abc(one)

%one

I put on my Missouri hat:
"Show me!"
and discovered not much until after a step boundary:

run;

after which I get the cryptic message:

value of x is one which is 1

I would have expected:
value of the macro abc parameter one is 1

what was that recent thread where we were discussing
whether one could communicate clearly in the
SAS macro unLanguage?

This is the knot in my statement at that time.

definitely something to hang on the wall
but knot readable and (so I conclude)
    knot reusable
